One of the culinary challenges I’ve heard people talking about is to make a meal out of ingredients bought entirely from somewhere that doesn’t specialize in food. Gas stations, convenience stores, discount stores, that kind of thing. Here is the rules that I’ve seen:
1) Ingredients must all come from a single location. Exceptions can be made for water, small amounts of salt, pepper, oil, and commonly-available, inexpensive dried spices.
2) Ingredients purchased must come in under a certain budget (I chose $10.00 before tax).
3) The meal should feed at least four adults.
4) There must be some actual cooking involved. You may combine ingredients from instant meals or canned goods, but they can’t be served as-is with no changes.
5) The meal should be as healthy as possible; it should not be able to be mistaken for a dessert.

There is a lot of food available at the local Dollarama, but most of it is junk food. Chips, candy, chocolate, soft drinks, that kind of thing. There is a small section near the back of regular food, but nothing is perishable. I wanted to include some fruit and/or veggies in the meal, and preferably a bit of meat if possible, so that narrowed my choices even further. I was tempted to make spaghetti with tomato sauce (there was both pre-made spaghetti sauce and canned tomatoes, tomato paste, and Italian spice mix), or canned soup/stew with Bisquick dumplings, or pancakes with canned fruit (there was pancake mix, coconut milk to replace cow’s milk, canola oil and applesauce to replace the eggs, and a couple of kinds of canned fruit as the topping). However, I finally decided on a tuna noodle casserole.

My ingredients were:
2 x Pacific Pride Flaked Light Tuna in Water 130g @ $1.00/ea
1 x Fruitropic Coconut Milk 398mL @ $1.25/ea
2 x Aylmer Vacuum-Packed Whole-Kernel Corn 341mL @ $1.00/ea
2 x Campbell’s Cream of Mushroom Soup 284mL @ $1.00/ea
1 x Buongusto Macaroni 900g @ $1.00/ea
1 x Old Dutch Original Potato Chips 40g @ $0.50/ea
Subtotal: $8.75 + tax
Total with tax: $8.82
(Only the chips were taxable.)

I was very happy with the end result, which I based on the Campbell’s® Tuna Noodle Casserole from Allrecipes.com. Of course, I had to make changes for the available ingredients, but I had to start somewhere. For example, I replaced milk with coconut milk, frozen peas with canned corn, egg noodles with macaroni, and the dry bread crumb and butter topping with plain crushed potato chips. Even so, it worked really well! I think that I will probably make this recipe again, but not in challenge-mode, so that I can use frozen corn instead of canned since I greatly prefer the taste of frozen.
As a bonus, it’s a great meal for camping (cooked in a pot instead of baked), cottaging, or when trying to clean out the pantry, since all of the ingredients are non-perishable. And at $2.21 a head (assuming it serves the minimum four people), it’s pretty darned affordable. Out of challenge mode, with a bit of bargain shopping at the supermarket, it could be made even cheaper. Around here, I know that cans of cream of mushroom soup often go on sale for $0.50 each, coconut milk is about $0.98, a big bag of frozen corn often costs about $2.00, and dried noodles sometimes go on sale for less than $1.00 a bag. This is all assuming you don’t buy the big name-brand version stuff, of course.
So here’s the recipe:

Dollar Store Tuna Noodle Casserole
Serves 4-6 adults
Fill a medium-sized pot three-quarters of the way with water. Add:
– a pinch of salt
Bring the water to the boil on the stove on high heat. Add:
– 2 1/4 cups dried macaroni
Turn the burner down to medium-high. Cook the pasta until it is al dente. Drain the pasta and set aside.
Preheat the oven to 400°F (205°C).
In a casserole dish that holds at least 2 quarts (1.9L), add:
– 2 cans condensed cream of mushroom soup
– 1 cup canned coconut milk*
– 2 x 341mL cans of whole-kernel corn, drained and rinsed OR 2 cups frozen corn
– 2 x 130g cans of tuna packed in water, drained and broken up with a fork
Mix well. Add the drained pasta to the sauce mixture, stirring well to evenly distribute the ingredients. Put casserole into the oven uncovered. Bake for 30 minutes or until warmed through**.
Remove casserole from the oven. Open and crush in the bag:
– 1 40g bag of plain potato chips
Stir the casserole. Sprinkle the crushed chips onto the top of the casserole and bake for an additional 5 minutes. Remove from oven and serve.
*Canned coconut milk tends to separate, so stir it well before measuring.
**If you are cooking this on the stove, heat mixture gently in a pot until it is warmed through and sauce is slightly thickened. Skip the next baking step, and instead garnish each individual serving with a sprinkling of crushed potato chips.
