When you're cooking from scratch you don't think so much of Fast foods but there are many basics that can create your own version of fast food.
About once a week I cook a crock pot full of black beans. These are my favorites others may choose another basic bean. I cook a big pot of boiled potatoes and about 2 cups of brown rice. With these in the frig some very good meals are quick to fix. One boiled potato goes in the micro wave while you take a scoup or two of black beans and place them in a pot. Add half a can of Hatch chopped tomatoes with green chili's and heat. When the potato is hot quarter it and pour the beans over the potato, add a little grated cheese and green onion and whalla there is a great meal. I love black bean burritoes with shredded green cabbage, onion and grated cheese. I also make a mushroom gravy with green sauce that I put over my brown rice. Very fast if it's all in the frig. Take a scoup of cooked brown rice in a bowl, add gravy and into the micro wave. Yum. Fried rice, potato fritata, potato soup, egg drop soup, egg foo yung all can be made very quickly with your basices. I also steam slices of sweet potato and find that when I need a snack I just slide the skin off of a cold cooked slice I have a very healthy quick snack.
Another quick food is take a package of ramon noodles and put in a fry pan with cover with water. Add a 1# package of frozen mixed vegitables. and cook together. Filling and good for you.
Home made bisquits are so quick and easy to do. I make whole wheat bisquits in the toaster oven and love to dunk them in coffee or cocoa or even hot milk.
These are some of the fast foods I keep on hand and meals are easily put together with little mess.
