In a bowl, combine the minced beef, diced onion, minced garlic, salt, black pepper, paprika, and 7 spices. Mix well to combine all the flavors.
In another bowl, mix the flour with 20 g of salt. Gradually add the oil and water, then incorporate the egg to form a dough. Knead until smooth.
Roll out the dough thinly and cut it into squares. Place a spoonful of the meat mixture in the center of each square.
Fold the dough over the filling to create a dumpling shape, sealing the edges tightly.
Boil the manti in salted water until they float to the surface, indicating they are cooked through.
For the yogurt sauce, heat the yogurt gently with the egg and minced garlic to prevent curdling. Season with salt, paprika, mint, cumin, and sumac to taste.
Serve the manti hot, drizzled with the yogurt sauce.
