Prepare the dough: In a large bowl, mix 2 cups of whole wheat flour, 1 cup of beetroot puree, 1/2 tsp of salt, and 1 tbsp of oil. Knead into a smooth, firm dough. Cover and let it rest for 15 minutes.
Make the filling: In a separate bowl, combine 1 cup grated paneer, 1/2 cup mashed green peas, 1/4 cup chopped cilantro, 2 tbsp green chutney, 1/2 tsp garam masala, 1/2 tsp cumin seeds, and remaining 1/2 tsp salt. Mix thoroughly.
Shape the envelope: Divide the resting dough into equal-sized balls. Roll each ball into a thin 6-inch circle.
Add the stuffing: Place 2 tablespoons of the paneer and pea filling in the center of the rolled circle. Fold the four sides inward to overlap in the center, creating a square shape. Seal the edges gently.
Pan-fry: Heat a skillet or tawa over medium heat. Place the folded flatbread on the pan. Cook until golden brown spots appear, then flip. Apply a small amount of ghee or oil to both sides and cook until crispy and fully cooked.
