4 large carrots, diced

3 stalks celery, diced

1 small zucchini, diced

23 cloves minced garlic

3 teaspoons Italian seasoning

1 teaspoon smoked paprika

1 teaspoon sea salt

3/4 teaspoon red pepper flakes

1 1/2 cups dried French green lentils (can sub brown lentils)

1 15-ounce can fire-roasted tomatoes (or plain crushed tomatoes)

4 cups low-sodium vegetable broth

Add all ingredients (except the red wine vinegar and filtered water) to slow cooker. Stir.

Cover and cook on high for 3 to 4 hours or low for 6 to 8 hours.
