When I worked. before I went to work I would put a couple of chicken breasts in the crock pot along with a couple potatoes and some carrots and cover with golden mushroom soup and cook all day. When I got home from work supper was ready. After the clean up I could get right to the sewing room.

Cook once and eat thrice!!!
.... cook larger portions on the weekends, and re-create them for weekdays and nights!

I don't look at it as Leftovers .... rather Planned Overs. It doesn't meant that it's the same thing re-heated, but instead giving them a new life in different menu items.

Its just the 2 of us, so while I do crock pot meals we do have a bunch of leftovers. But I'm sick of the crock pot stuff we like too, lol.

I think we ought to look into more salads with shrimp or crab, that would be super quick and easy...

In a casserole dish put 2 skinless boneless chicken breasts, covered in your fav frozen vegy, dump a can of Campbells Mushroom soup (mixed with a can of milk) ......... bake til done........ prep time about 4 min tops!!!!

Not an expert at doing ahead, but one thing I do is double the amount of bacon I would need. And freeze the remaining. I bake the bacon and not fry it, so cooking more is easier than on top of the stove. I also cook more ground beef than I need and freeze, you can take it out and use for a lot of recipes. I freeze leftover gravy, too. It freezes well.
Another thing if I have too many mashed potaotes, mix up my leftovers with an egg, sour cream, shredded cheese, ontions and freeze it for a side to a future meal. Just a few ideas.

With the bacon it is so handy for all of us, to take a couple of strips out and warm in the microwave for sandwiches and salads.

One of our favourite go-to quickies is sloppy joes, done the way my mother in law made them. Brown 1 pound of ground beef, drain fat, add a chopped onion and cook until soft, you can add some celery too if you like. Pour in 1 can of Chicken Gumbo soup (no water), 1/2 cup of chili sauce (or salsa if you want a bit of heat), 1 TBSP mustard. Heat through and serve on buns with potato chips and pickles on the side. This has been my DH's favourite since he was a kid and I like it too, so do my boys.

Buy a crock pot and work your way through the cookbook. You'll never eat frozen again.

I always buy ground beef on sale. Then I cook it up when I get home, (you could do this on a weekend day), adding in garlic, onions and seasoning. I drain the fat and freeze, (I use freezer bags - quart size - and pat flat), when I need something quick I take one of these out of the freezer and make it into, chili, hamburger stroganoff, taco salad, sloppy joes, you get the picture, this way, the hardest work is already done.

Quick suppers
 

I sometimes make hot weinies and potato salad, or chicken and rice casserole for a Rice A Roni mix and instant potatoes. I make small pans of lasagna and freeze them.
