I swear I live in the kitchen. Between making lunches, meals. clean up, the kitchen can be where I spend hours a day. I am always trying to save the amount of time I have to spend in there for more enjoyable pursuits like the garden.
Whenever I make a meal that could possibly be frozen, I make enough for two meals. I am a huge fan of freezer cooking.
Keep the pantry stocked with enough to be able to double your meals. For us that is two large meals but for smaller families that may be splitting a single pan in two.
When I am done I just cover with plastic wrap and seal with foil writing the date and meal on the foil.
Whenever you are chopping up veggies for dinner, cut up some for lunches. I just toss them in the fridge and they are ready for me to grab in the morning when I make lunches.
I do the same with snacks for lunches. I fill several bags at once in place in a plastic bin in the snack cupboard. That way when lunches are made, we can grab one quickly.
