Kim, Hi!
Depends on how well you pack foods to freeze! Most anything can be frozen for 3 months without a problem. Make sure there's no air...6 months. Vacuum sealed things can go a year or longer. There isn't much that can't be frozen.... Most things do just fine. I have only come across one thing that didn't freeze well and I can't even remember what that was!
Chicken or any protein that is boneless (ie, pork, venison, elk, turkey, hamburger, fish, etc) can be prepared quickly and easily. You just brown it in a skillet (remove from skillet), dump in some of your favorite veggies (on hand) and saute, then add chicken broth, white wine, lemon juice, apple juice, water or milk and scrape all the bits off the bottom and you have a sauce that you can thicken with just a bit of butter. Just change the veggies and the seasonings for any flavor you like.
Here's some ideas:
Seasononing: Cumin, chili powder, garlic powder. Add green chilies, diced onion and bell pepper and saute then add chicken broth and you have Mexican!
Seasoning: Seasoned salt. Use green pepper, onion, black olives and jarred spaghetti sauce and you have Italian!
Seasoning: Paprika, curry powder, and garlic. Saute, raisens, onions, cranberries for Indian!
Seasoning: Ginger, garlic, and red pepper. Saute, baby corn, celery, bamboo shoots, broccoli, pineapple, add chicken broth and you have Oriental!
Seasoning: Seasoned salt. Saute broccolli, baby carrot, and onion add Lemon juice and chicken broth and you have Californian!
You can do this in about 30 minutes. Just have a pasta, potato, beans or rice , a tossed salad and you have the full meal deal!
