- 2 medium to large sweet potatoes, chopped (about 1 pound; I leave skin on, but peel if desired.)
- 1 cup dry brown lentils
- 1 small to medium onion, diced (red or yellow)
- 4 cloves garlic, minced
- 2 teaspoons minced fresh ginger (could use 1 teaspoon if you prefer a more subtle ginger flavor)
- 3 (14-oz) cans chicken or vegetable broth (plus extra to thin any leftovers as the lentils will continue to absorb liquid once cooked)
- 1 (14.5-oz) can diced tomatoes, undrained
- 1 (15-ounce) can 100% pumpkin puree (or 2 cups fresh puree; not pumpkin pie filling)
- 1 tablespoon curry powder
- 1/4 teaspoon red pepper flakes (use 1/8 teaspoon for less spice; may substitute a jalapeño pepper, seeded and finely chopped)
- 3-4 cups lightly packed kale or spinach, stems removed and roughly chopped
- 2 tablespoons honey (may substitute brown sugar)
- 1 teaspoon kosher salt and freshly ground pepper to taste
- Optional garnishes: plain yogurt or sour cream
