Cut the leftover rotis into triangular shapes with a pizza cutter or a sharp knife.
Heat the oil in a deep frying pan or wok over medium heat.
Once the oil is hot, add a few roti triangles to the pan at a time.
Fry the roti triangles until they turn golden brown and crispy, stirring occasionally to ensure even cooking. This should take about 2-3 minutes.
Remove the fried roti triangles using a slotted spoon and place them on a paper towel-lined plate to absorb any excess oil.
While the roti nachos are still hot, season them with salt, red chili powder, and chaat masala to taste. Toss the nachos gently to ensure that the seasoning is evenly distributed.
Serve the roti nachos immediately with some salsa or chutney.
Notes
It's also worth noting that while Roti Nachos can be a tasty snack, they are high in calories and fat due to the deep-frying involved. If you're looking for a healthier snack option, consider using an air fryer instead of deep frying or choosing a snack that is lower in calories and fat.
