Bite-sized squares of sweet onions are topped with a mild and savory blend of pork, shrimp, water chestnuts and sweet peppers, and steamed.
About 20 water chestnuts (canned are okay; drain well), finely chopped to measure 3/4 cup
Place the chopped chestnuts in a bowl and add the pork, shrimp, green onion, sweet onion, ginger, cilantro, bell pepper, garlic, soy sauce and egg white. Mix well.
Cut off both ends of the Oso Sweet and discard. Cut the onion in half lengthwise, then place each, cut sides down, on a cutting board. Cut down through each half, creating 1 1/2-inch wide slices. Separate the slices and cut each one as closely to 1 1/2 inches wide as possible, so you create 1 1/2 inch square bases.
On the inside surface of each square, mound about 2 tablespoons of the filling. Place the squares on a steamer rack and place the rack in a pan over boiling water. Cover and steam until the filling is fully cooked, about 10 minutes.
Remove to a platter or individual plates and serve hot with soy sauce or a mixture of soy sauce, sesame oil, and chili-garlic sauce.
Yields about 32 pieces of Dim Sum
