"Daal Puri" is my favourite tea snack.
Daal Puri is a Bangladeshi snack. First, we boil the lentil with onion, salt, garlic, turmeric, and chilli. Coriander leaf is optional. You have to give less water, so it soaks almost all the water and leaves the boiled, soft wet lentil. Then, we make tortillas with flour, a pinch of salt, and oil. Then make a small tortilla or roti. Put a teaspoon of lentil paste in the middle and cover it with the rooti like momo. Then again, with the roller make small rooti. In the end, fry it in the oil. Your puri is ready.
This is the typical recipe. You can make it in many different ways.
I like to take it with salad/salsa and tea.
