If you can read and follow directions, you can be an excellent cook.
I any case, great suggestions above. One that I will add is literally anything in a crock-pot. You can eat like a king with a crock-pot and it is simple. Google crock-pot recipes.
One that you can try is:
Pot Roast of Beef
3-4 pound brisket, rump roast, or pot roast
3 potatoes (chopped or by a bunch of smaller russet style potatos)
3 carrots (chop 'em)
1-2 onions, cut up
1/2 cup of water
salt and pepper to taste
Put vegetables on the bottom first. Salt and pepper the meat, then put it in on top of the veggies. Add your water. Cover and cook on LOW for 10 hrs. Don't open the lid till it is done.
If you like beans, go to the store and by a bag of uncooked beans. You can get a pound for a couple bucks. Cook those in a crock-pot. Cheap and easy.
