All good advice, but if you're going to bake or grill meat, please buy a meat thermometer and look up the temperatures on line. You might also consider purchasing a small crock pot. They're wonderful for cheap cuts of beef roast, and you can throw in some carrots and potatoes. It can cook during the day, and your feast will be ready when you get home. To make chili in the crock pot, use tomato soup or spaghetti sauce. Add the canned kidney beans, and let it simmer on low all day. Fry and drain the hamburger and add it to the mixture in the crock pot when you get home. Corn bread is easy to make if you get the Jiffy brand in a box.
Boiling boneless, skinless chicken breast and adding a can of cream of chicken soup after the chicken is tender makes great creamed chicken. You can buy the biscuits in a can or boil some egg noodles to go with it. Baking pork chops with cream of mushroom soup is good too.
You probably don't have a lot of storage bowls, so freezer bags will be your best friend in the kitchen. You can use them to repackage large packages of meat you find on sale as well as to store leftovers.
Making a turkey or pork roast isn't difficult, and you can store individual servings in freezer bags to eat as a meat for dinner or to make sandwiches and salads with, (which is a lot healtheir than deli meat).
Depending upon what kind of kitchen set up you have, you'll need to invest in a few pots and pans. If you have no oven and have a fondness for large meats and poultries, you may want to invest in a roaster. My husband just bought me one a few months ago for $29. I can make a 22-lb turkey or a whole pork roast in it.
Go to the dollar store and get your spices...cheap, cheap, cheap! Onion soup mix is great with ground beef. They also have steak and chicken seasonings.
You can even make desserts without a mixer or oven. Google the recipe for No Bake Cookies. Pudding can be cooked in a small sauce pan or shaken in a closed containter and then chilled, (just make sure to note whether the box says cook and serve or instant).
