With the weather warming up, I am cooking beef, chicken & pork roasts then shredding/slicing and packaging in meal-size portions for the freezer. On hot days it is a quick and easy to grab a bag of shredded chicken or pork for a meal-can be reheated in the microwave or put on buns and wrapped in foil on the grill.
When the weather is cool, I will make up pot pies, baked ziti, lasanga & chilli and put pans in the freezer. These would be heated in the oven.
I also bake bread and muffins when it is convenient for me (or when it is cooler) and then thaw for use without heating up the kitchen on hot days.
