You can, of course. Add a little olive oil to the skillet or coat it with cooking spray as it heats up over medium heat. Place the patties in the skillet and cook for about 4-5 minutes on each side or until they are thoroughly cooked and golden brown. Depending on the size of your skillet, you might have to cook them in batches. Once cooked, transfer the patties to a plate lined with paper towels to remove any excess oil.
