How to Make
This Italian summer soup is very easy to make after you have chopped all your veggies!
To do it, melt the butter in a large pot set over medium heat.
Once the butter melts, stir in the onions, garlic, and celery.
Saute the veggies just until softened and the onions are translucent.
Once the onions and celery are soft, stir in the squash and zucchini.
Season the veggies with the dried basil, oregano, salt, pepper, and crushed red peppers.
Then stir in the can of diced tomatoes, tomato sauce, and broth.
Bring to a boil then reduce the heat to low and simmer, just until the squash is tender, roughly 10-15 minutes.
Serve warm with crusty bread and enjoy!
