roast a few chickies, quarter them up.
bbq is very freezer friendly.
Lasagna, sure-
I tend to stay away from freezing things with most veggies, and do mostly meats. Not a fan of many frozen veggies at all. Might wanna do a package type thing? A meat along with a frozen item that rocks?
Suggestions on frozen sides in bags:
Trader joe's gnocchi with spinach and peas in spicy (it's not spicy at ALL) sauce
Tj's polenta with carrots (it's got other stuff in it)
Tj's gnocchi with mozzarella
Seriously tho -
If you are a smoker,
ribs
pulled pork
smoked chickens
My freezer is always full of portions of those come winter. Freezes real nice. I thaw/nuke a meat, throw some frozen side in a pan, and steam a green veggie or cauliflower in the world's best steamer (your microwave) when I need a 10 minute meal that has some pride in it.
We cannot be friends if you do not know the difference between Mayo and Miracle Whip.
