Heat 2 tsp of the oil in a nonstick skillet over medium-low heat.
In a shallow baking dish, whisk together the eggs and milk. Dip two of the sandwiches in the egg mixture, turning to coat, and place in the skillet.

Transfer to a baking sheet and cover with foil to keep warm. Repeat with the remaining oil, egg mixture and sandwiches.
