I am definitely in that boat, but have gotten a lot better. Here are two of my favorites:
SPINACH SOUP (Adapted from a Cranks cookbook)
Ingredients: 1 ea. onion, zucchini, sweet potato; big handful or two of spinach, 5 cups broth, 1/2 cup of cream*
Chop everything up. Saute onions, and zucchini in some olive oil. Add the sweet potato, spinach, and broth. Bring to a boil, then simmer for 20 minutes or until potatoes are soft. Add cream and blend everything together (either in batches with blender or better yet - an immersion blender)
* I use cashew cream and it's mighty tasty. Cover about 1/3 cup of raw cashews with water and let soak for 20 minutes. Drain, rinse, then add fresh water to cover and whir in blender until smooth. Great for lots of other stuff, too!
VEGGIE PESTO (adapted Super Natural Cooking by Heidi Swanson)
Ingredients: bunch of asparagus, big bunch of spinach, 1 cup pine nuts, 1 cup parmesan cheese, 2 cloves garlic, 1/4 cup olive oil, squeeze of lemon
Snap the aspargus and cut in half. Add to boiling water and cook for about 2 minutes. Throw everything except the olive oil and lemon into a food processor (I do the spinach and stuff first to make room for the asparagus). Pulse until you get a nice paste, scraping the sides as needed. Add olive oil and lemon and process some more. Add more olive oil if needed to get the desired consistency. Goes great on pasta or quinoa (my usual).
I make these two often enough that I typed all that from memory, and I'm horrible at memorizing recipes!
Another thing I try to do is basically keep a salad bar in the fridge. Chop a bunch of stuff up on Sunday, then it's ready to go in whatever version you want that day.
Enjoy and good luck!
