In a bowl, marinate the onions in the lime juice at room temperature for 30 minutes. Drain the onions in a sieve and reserve the marinade. In a heavy skillet, melt the butter over medium heat. When the foam begins to subside, add the onions. Stir frequently and cook for about 5 minutes or until the onions are transparent. Stir in the chilies and garlic, reduce the heat and cover the skillet. Continue cooking for 10 minutes or until the chilies are tender. Turn off the heat and add the reserved marinade. Cool to room temperature before serving. Makes 1_1/2 cups.
