In a bowl, combine the shredded cabbage, chopped onions, salt, black pepper, and 2 tablespoons of oil. Mix well.

In another bowl, sift the all-purpose flour. Add 3 tablespoons of oil and salt, then knead into a dough as you would for making flatbreads.

Divide the dough into 3 portions. In a small bowl, mix orange food coloring with a little water. Add this to one portion of the dough and mix well to color it orange.

In another small bowl, mix green food coloring with a little water. Add this to another portion of the dough and mix well to color it green.

Roll out each colored dough portion into thin sheets. Take a small piece of dough, roll it into a small circle, place some cabbage filling in the center, and shape into momos. Repeat with the remaining dough and filling.

Grease the stainless steel steamer basket with the remaining 1 tablespoon of oil.

Pour water into a pot, add the lemon wedge, and place the steamer basket with the momos on top. Cover and steam the momos until cooked through.

Serve the tasty momos hot with Schezwan chutney or tomato sauce.
