Oil
2 onions
2 large carrots
2 ribs celery (if available)
1/2 can tomato paste
1 quart canned tomatoes
1 can black beans
1 cup seasonal vegetables (corn, squash, zucchini, green beans, peas, etc)
Enough vegetable broth to make it soupy
Garlic
Oregano
Thyme
Salt
Black pepper
1 cup dried pasta
1 cup greens (eg spinach)
2 tsp lemon juice
Freshly grated Parmesan cheese
In a large pot, add oil, chopped onion, carrot, celery, and tomato paste. Cook, stirring often, until the vegetables have softened and the onions are turning translucent, about 7 to 10 minutes.
Add everything else except the lemon juice, greens, pasta, and parmesan cheese, and simmer until nearly cooked.
Add the pasta and greens and cook until pasta is done. Add lemon juice and plenty of parmesan, to taste.
