Zucchini and Beans with Pasta

One of my favorite things about summer is the bounty of available fresh vegetables at low prices. Our farmers' markets are full of zucchini and yellow squash. The beans and pasta in this recipe make a complete protein and a cheap, delicious meal.

1/2 pound of dried Great Northern beans
6 cups sliced zucchini
2 T olive oil
1 medium onion, chopped (any color)
1 large garlic clove, smashed
1 29 oz can of tomato puree
3/4 cup water or vegetable broth
Salt and pepper
4-5 fresh basil leaves OR 1/2 tsp dried basil
Dash of crushed red pepper flakes (more if you like extra kick)
1 pound elbow macaroni or other small pasta
Grated Romano or Parmesan cheese (optional)

Prep: Soak beans overnight
1. Cook beans according to package directions. Drain, reserving 3/4 cup of the cooking liquid.
2. Start heating heavily salted water for pasta.
3. In a large pan, on medium heat, cook the onion in the olive oil until it begins to soften. Add garlic and red pepper flakes. Cook until the garlic becomes fragrant (about 30 seconds). Add zucchini and saute, until slightly softened.
4. Add tomato puree, water or broth, reserved bean broth, salt and pepper. Bring to bubbling. Simmer for 10 minutes.
5. Add beans and basil. Cook 5 more minutes. If it is too thick, add water.
6. Place cooked and drained macaroni into a serving bowl. Spoon 3/4 of the sauce over the pasta and mix. Pour remaining sauce over the top and sprinkle with grated cheese, if using.
