Kathi Roll is a popular Indian street food wrap with a flavorful vegetarian filling in a flaky paratha. This satisfying snack is perfect for family outings and makes a fun, portable meal.
Mix all-purpose flour with 1/4 tsp salt and water to form a smooth dough; cover and rest for 15 minutes.
Boil potatoes until fork-tender, then peel and mash; finely dice onion, bell pepper, carrot, and green chili.
Heat 2 tbsp oil in a skillet over medium and sauté onion, bell pepper, carrot, and chili for 2-3 minutes until they begin to soften.
Add mashed potato, 3/4 tsp salt, garam masala, chaat masala, chili powder, black pepper, and half of cilantro. Stir well and cook for 3-4 minutes. Allow filling to cool slightly.
Divide dough into 4 balls; roll each into a thin circle and cook on a skillet with a little oil over medium-high until both sides are golden brown and paratha is flaky.
Spread vegetable filling down center of each paratha, sprinkle with remaining cilantro, and roll up tightly. Optional: briefly toast each roll in the skillet for extra crispness.
