Gently start to roll and flatten in your hands, seam side down. Do not squeeze or push to hard or the beans will come out. You want to shape and flatten to resemble a long, flat football. Place flattened tlacoyos on hot surface. Cook for 2 to 3 minutes per side or until you get some browning. Drizzle a little oil over tlacoyos, they will begin to crisp and fry. Turn as needed. Serve right away. Garnish with salsa.
Tlacoyos can be prepared ahead of time and cooked on the comal as instructed with no oil. When ready to serve, flash fry in some preheated shallow oil.
