Add peeled and chopped beets and 4 Tbsp. water to a microwave-safe bowl.
Steam beats by microwaving on high for about 10 minutes or until soft.
Heat a large pot on medium heat. Add garlic, onion, carrots and 2 Tbsp. water. Sauté for five minutes. Stir frequently. Add more water if necessary to prevent sticking.
Add cooked beets, water and spices to the pot, and cook, covered, for 10 minutes, stirring occasionally.
Add diced tomatoes and kidney beans to the pot, and bring to a simmer. Cook, covered, for 50 minutes, stirring occasionally.
Top with optional garnishes before serving, if desired.
