Grill zucchini and corn in Bull Grill until lightly charred and then set aside.
Use your Bull side burner to heat a heavy bottom pan over medium heat. Stir in tomatoes, chicken broth, & Bull Sweet Heat Rub. Bring to a boil, reduce heat to low, and cover. Let the soup simmer for 20-30 minutes.
Add tortellini and simmer for about ten minutes, until pasta is tender. Finish off the soup by adding grilled corn, zucchini, squash, lentils, and spinach and let simmer for 5 minutes. Season with salt and pepper to taste.
