In a large frying pan, heat oil over medium heat, about 1-2 minutes.
2. Add sausage, breaking/crumbling with a wooden spoon as you go, until evenly cooked and browned, about 4-5 minutes.
3. Reduce heat to low and add whisked eggs. Scramble until just set, about 2 minutes.
4. Sprinkle cheese evenly over eggs and cook over medium heat until melty and slightly browned, about 2 minutes.
To Char Tortillas
Heat a gas stove burner on medium high and place corn tortilla directly on the burner. Watch carefully and flip with tongs once the tortilla begins to brown/bubble (this will be FAST). Once both sides are charred, remove to a serving platter and repeat with remaining tortillas.
To Serve
Serve with cubed avocado, sliced scallion, cilantro leaves and your favorite hot sauce
