Here's an old favourite of mine. No one can say this isn't flavourful! Oh, and don't be shy of using green beans in soup - I was at first, then I was like "Oh, this is perfectly fine"
Adapted from I Eat Food
Veggies: Onion, carrots, garlic, green beans
Then came tomato sauce, diced tomatoes, a bit of soy sauce, water, veggie bouillon, celery seed, thyme, Old Bay seasoning, a spicy spice mixture, and quinoa. And pinto beans.
Lastly, thickened with a corn starch slurry, and served with veggie meat... and I am happy.
