There have been previous discussions on this topic, but darned if I can find one of them right now.
There are several recipes in Nava Atlas'
Vegetarian Soups for All Seasons that I find freeze well, especially now that fall is upon us, or, LOL, many of us. The page numbers correspond to the 2006 edition:
Curried Red Lentil Soup, p. 27
Moroccan-Style Vegetable Stew, p. 33
Three-Bean Soup with Brown Rice, p. 69
Hearty Barley-Bean Soup, p. 71
Tomato, Lentil, and Barley Soup, p. 72
Curried Lentil, Potato, and Cauliflower Soup, p. 73
Four-Grain Tomato Soup, p. 74
There are others on my list to try. As there is just the two of us, I often freeze whatever soups or stews that I make, as well as the chilis that my husband makes. I don't like the texture of frozen summer squashes or pastas, so I don't freeze dishes that contain those things, personal preference.
We are very fond of Indian cuisine. Dals I always freeze. With them I do as merriweather describes, freeze the quart freezer bags flat, they stack vertically oh so very well in the ice machine bin that we never use for ice.
When we had a house, I always just chopped tomatoes and froze them in the quart bags, pre-measured for soups. I no longer have a garden, so that's not an option, but I do still do fresh corn cut off the cob that way. Ah, summer's taste in the cold of winter,
Have fun.
