My go-tos:
Pumpkin soup
Steamed spinach with a small pat of butter and lemon-pepper seasoning
Broccoli soup
Cream of spinach soup
Snap peas stir fried in oyster sauce
Asparagus with hollandaise sauce (just a tiny smidge)
Red cabbage and carrots, both shredded, with rice wine vinegar, sugar, and soy sauce dressing
Sliced bell pepper with hummus
Roasted beets with goat cheese
Lenil vegetable soup with bok choy
Vegetable hot pot (google recipe, it's the first that comes up on Eating Well website)
In regards to the Campbell's soup reference above, you would get a lot more nutritional value if you made your own. Making homemade soup is very, very easy and worth the increased nutrients you get from fresh versus canned soup.
