Set a large 6-8 quart soup pot over medium heat. Add the olive oil, onions, garlic, mushrooms, and carrots. Sauté for 5-8 minutes to soften the vegetables, stirring regularly.
Place the whole chicken breasts down in the sautéed veggies at the bottom of the pot. Add in the chicken broth, water, canned tomatoes, red wine, Italian seasoning, 1 teaspoon salt, and 1/4 teaspoon ground black pepper. Bring to a boil and simmer for 15-20 minutes, until the chicken breasts are cooked through.
Remove the chicken breasts with tongs and set on a cutting board. Add the zucchini, summer squash, canned beans, macaroni, green beans, and roasted red peppers to the pot. Stir well. Bring to a simmer and cook for another 5-8 minutes, until the pasta is cooked through.
Meanwhile, chop the chicken into bite-size pieces. Stir the chicken back into the soup. Taste, then salt and pepper as needed.
NOTE: If making a gluten-free variation of this recipe, make sure to use a GF pasta that will not disintegrate in the soup. (Both ALDI and Trader Joe's have a pretty hearty GF pasta.)
