I also make and freeze meatloaf, but I have a slightly different way.
I buy ground beef/hamburg on sale in bulk.... to it I add my usual Meatloaf ingredients, which for my family has included soy meat substitute, oatmeal, breadcrumbs, leftover mashed potatoes, leftover cooked vegetables, potato flakes, soy sauce, worcestershire sauce, eggs, ketchup, etc etc etc!
I use mini loaf pans because it works best for me.... I take one mini loaf pan.... line it with saran wrap, fill it with the meatloaf mix, pack it down, level it off, and tip it over onto a foil-lined jelly roll pan... and continue doing this until I have used all the meat mix.... the saran wrap helps keep the meat from sticking to the pan. I usually make about 20 meatloaves at once. I cook them all at once. After they have cooled I wrap them in saran wrap and then in foil... label and freeze.
When I am ready to use them I just defrost (either by leaving in the fridge or by microwave) and microwave until heated through. Add instant mashed potatoes or rice or whatever to the side.
With my method you only have to heat up your oven once to make 20 meat loaves.... we have very expensive electricity up here in NH, so that really helps!
Chicken is a bit tougher to make and freeze... I find it gets dry if cooked more than once. Your best bet there would probably be using the crockpot. I LOVE myself when I actually am organized enough in the morning to use my crockpot!
My easy version of chicken cacciatore for the crockpot.
chicken parts without the skin (whatever is cheapest.... usually leg quarters around here)
canned/jarred spaghetti sauce
sliced onion/peppers (buy presliced at the salad bar if you want)
If time permits sautee the veggies in a pan with a bit of oil before adding to crock pot. Otherwise I just soften them in the microwave for a few minutes.
Put chicken in bottom of crock pot.... pour spaghetti sauce over to cover... add veggies. Cook for several hours (in crockpot).
Serve with a side of cooked pasta to pour the sauce over!
I discovered that you CAN freeze lots of things you might not think of. I was PG with DS at Christmas time (he was born in Jan.) and when our family Christmas dinner was done I was offered all the leftovers for the freezer. I jumped at the offer! I froze cooked chicken with sauce, rice, all kinds of stuff... and it was all just fine when defrosted and reheated.
Best of luck with the new baby and with the cooking! .........P
