Mix flour and water to form a dough.

Knead the dough until smooth.

Optionally, add spices to the dough for flavor.

Cover the dough with a wet towel or plastic wrap and let it rest for 30 minutes.

Combine ground beef, chopped onion, spinach or cabbage, minced garlic, grated ginger, chopped green onions, chopped cilantro, and salt for the filling.

Bring a large pot of water to a boil.

Divide the dough into 12-18 pieces.

Roll each piece into a small, flat circle.

Place a spoonful of filling on each dough circle.

Fold the dough over and crimp the edges to seal the momos.

Place the momos in a steamer basket.

Steam on high heat for 30 minutes, or until cooked through.
