Vegetable soup is always a good standby. You can throw anything into it and eat it either as it is or blend it for a smoother soup (I often eat it in the summer blended and cold). I make mine in a slow cooker. Change up the recipe to use up any vegetables you have, but here are some suggestions.
Vegetable Soup
I start off with a can of diced tomatoes
Cabbage is a main part of the soup (lots of fiber)
Add beans (if they are dried, soak them first)
Carrots
Onions
Garlic
Kale or spinach
Chicken bouillon (add as much as you need)
Note: I keep a bag in the freezer and add leftover vegetables. I use these in the soup.
