Use 1 cup of cooked lentils(brown or green), Or use 1.25 cups of cooked chickpeas, lightly mashed to make a coarse texture instead of red lentils.
Add other veggies instead of potatoes such as zucchini, fennel or celery.
Canned tomatoes: Traditional Indian recipes usually use fresh tomatoes and are written for fresh tomatoes. Canned tomatoes have a stronger and sweeter flavor profile and usually overshadow some spices. Double the spices for canned.
Heat: The heat in this dish comes mainly from black pepper and the garnish. To adjust, reduce the black pepper to preference and omit garnish.
For additional heat, add 2-3 dried red chilies with the ground spices.
