Preheat oven to 300 degrees F.
Place four plates in the oven to warm. Combine eggs, salt and milk in a shallow dish. Add tortillas one or two at a time, and soak them as you would French toast, turning once to coat them evenly.
Heat about 1 tablespoon each of the butter and oil in a heavy skillet. Fry tortillas one at a time, cooking until they are browned lightly on each side and adding more butter and oil as needed. Place a pair of tortillas on each of the plates, arranging them side by side, but overlapping a bit. Don't cover them.
Top the tortillas with salsa, some chunks of avocado, and a generous sprinkling of cheese. Serve immediately. |
