Some people that do 30 days of cooking decide to prepare mixes, combine ingredients for recipes, add marinades to meat, etc. and then freeze the foods uncooked. Later on, they defrost in the fridge, transfer to a cooking dish, and cook the food.
Freezing pre-cooked items will not work for me. One of the things keeping me from cooking when I get home from work is the fact that I have to wait for something to cook. For me, I like to have dinner completely cooked when I get home. I’m fine reheating things in the microwave or preparing dishes that cook in about 15 minutes of less. Cooking chicken and then cooking a casserole with that chicken takes way too long on a work night.
Therefore, I completely cooked fajita meat, chicken, chicken noodle soup, meatloaf, and a casserole before freezing them.
The beauty of having cooked, cubed chicken in the freezer is that it can be added to a casserole for a quick dish. Cooked fajita meat is great for fajitas, pizzas, quesadillas, and salads.
