Peel and wash the bottle gourd. Grate it and mix with salt. Set aside. Peel, wash, and finely chop the onions.

Heat oil in a pan and sauté the onions until golden brown. Turn off the heat and let cool.

Squeeze out excess water from the grated bottle gourd and mix it with the sautéed onions. Finely chop the green chilies and add them along with the ghee. Grate the cheese and mix it in.

Sift the flour and gradually add water to make a soft dough. Divide the dough into small balls and roll each into a thin, round disc. Place the bottle gourd filling in the center, shape as desired, and seal to make momos.

Boil water in a large pot. Grease a steamer basket and place it over the pot. Once the water is boiling, arrange the momos in the basket, cover with a plate, and steam.

Steam for 10-12 minutes. Prepare all the momos in the same way. Serve hot with tomato chutney and salad.
