Any tips for a hungry grad student? I'm not afraid to cook, though I don't have all that much time (or spending money). Extra points for deliciousness, ease of preparation, health and price/serving. To throw my own favorite out there:
-6 bolillo/hoagie rolls
-pasta sauce
-fresh grated cheese (cycle through mozz, colby, jack, cheddar)
-pepperoni (or chicken/ground beef if it is around)
Make sure to put the pepperoni on before the cheese, and season liberally with salt and pepper.
These are easy to make and heat up, total cost is ~$6 for ~4 filling meals.
