Jen - I'm sorry to hear about your mom!
: Sending you good vibes!
As for frozen healthy meals, I agree with Suzanne, I make a lot of meals and freeze them individually to have on hand for a quick meal or lunch when I don't have time to prepare anything.
Some of the things that I make that freeze well are as follows:
Shepards Pie (Extra Lean Ground Beef, Canned Corn and Mashed Potatoe (with skim milk, Molly McButter)
Anything with Pasta (Spaghetti, Veggie Lasagna, etc.)
Roast Beef freezes well with some Potatoes
If you're looking for a store-bought frozen meal...
-Bistro Classics (these are amazing, just watch the fat content, its high in some of them)
-M&M French Onion Soup
-Deliscio Pizzas (you can get individual size ones)
Hope this helps with a few ideas...
