I generally have frozen cookies and cupcakes in the freezer, as well as waffles,pancakes, biscuits and muffins. I sometimes boil eggs, rice, and microwave potatoes in advance of when I need them. I chop onion, celery and green peppers and keep them in a plastic container in the fridge. Sometimes I make my piecrusts in advance and brown ground beef and freeze. This week I made pea soup and homemade baked beans and froze them. This saves me a lot of time and money as I'm less apt to suggest we go out to dinner or order in, when I can throw together something fast.
