Flavor Base: Heat oil in a large pot over medium heat. Add onion, garlic, and zucchini to the pan, cooking until onion and zucchini are a bit soft, about 5 minutes.
Stewify: Stir in marinara sauce and beans. Continue cooking, covered, for 5 minutes until marinara sauce is hot and gently simmering.
Greens: Stir in chopped kale and basil. Cook until kale wilts, about 2 minutes.
Serve: Season with salt and pepper, as needed, then serve warm!
Notes
*I like using one zucchini and one yellow squash for a fun color variation.
