This is a wonderful Cuban Style (Hamburger recipe). A family favorite, this comes from a friend from Florida by way of Cuba. It has unqiue taste that sets is a part from all the others, and everyone who tries this Hamburger wants this recipe. There is no question this is my top recipe for the grill in the summer. Note, this recipe makes 6-8 regular sized burgers or 4 really big ones for a hungry people! I also use Walla Walla Sweet onions if you like a sweeter flavor in your onions. Tip with chedar cheese, colby-jack for even more flavor. SERVES 4 -8
