Here are some basic healthy meals that most folks could make from their pantry supplies, to get you started.....
Pancakes (made from scratch or from Bisquick or other baking mix.... could be made healthier with whole wheat, etc). Serve with applesauce (homemade or jarred) or fruit.
Rice and beans.... so basic, so easy, so cheap, and I love it! Lots of different combos available with brown rice, wild rice, white rice (although that would be the least healthy), black rice... and of course pinto beans, black beans, kidney beans, etc. Jazz it up by cooking the rice with stock (chicken or vegetable, homemade or canned), add cilantro, lime juice, chili powder, etc.
Pasta.... top with a wide variety of things.... obviously red sauce/marinara sauce (homemade from scratch or from canned tomatoes, jarred sauce, etc), light white sauce (homemade from lowfat milk and parmesean cheese), tuna (a la tuna casserole), or just a bunch of diced and sauteed veggies (try mixing some sauteed onions and peppers with a can of diced tomatoes.... cheap, fast, and yummy!). You can google recipes for "baked" pasta dishes too.
Canned soup... if it isn't exciting enough, try doctoring it up with some other pantry ingredients..... tomato soup can become tomato tortellini soup by throwing in a can of diced tomatoes and some cooked frozen tortellini.
Semi-homemade vegetable soup... start with stock/broth or vegetable juice (V-8 or tomato).... add in whatever veggies you have on hand... carrots, potatoes, onions, peppers, corn, peas, beans, cabbage, celery, tomatoes (fresh, frozen, leftover, canned all work). Dig through your freezer for those lost bags with just a handful of veggies in each of them. Serve with some grated parmesan to sprinkle on top and a few homemade biscuits (made from scratch or using Bisquick).
Fried rice.... cook up a nice big batch of rice (brown is my choice)... grab a handful of leftover cooked meat (ham, chicken, pork) or canned meat... or tofu, plus some diced up veggies (peas and carrots are great, but corn or even broccoli work well) and a scrambled egg or two. Stir-fry all together and add some soy sauce. I do like to splurge and and add some chopped bok-choy.
Dig around in the pantry and find those things that you thought you might never use and find a way to use them! You will be so pleased with yourself!
I'll try to come up with some other ideas when I know what you have on hand.............P
