Heat a pot over medium heat, add rinsed red lentils and 2 cup of water. Cover and simmer until cooked. Drain the water.
In a bowl add cooked red lentils, lemon juice, chaat masala, cumin powder, serrano chili, cilantro, salt and mix.
Pour water in a bowl, large enough to dip a sheet of rice paper.
Place a rice paper in the water and let it soak for 30 sec. Remove from the water, shake off the excess and place on a flat surface.
Spoon red lentil mixture to the bottom 1/3 of the rice paper, top it with carrots, red cabbage and spinach leaves.
Gently pull the bottom of the rice paper over the filling, tuck the filling in and roll. Fold in the sides of the rice paper. Gently but tightly roll like a burrito.
Enjoy with a dip of your choice.
