In a medium bowl, combine eggs with 2 tablespoons of I Can't Believe It's Not Butter®, whisking briskly for 2 minutes, until eggs are frothy and spread is in small chunks.
Heat a large skillet over medium, then add remaining tablespoon of spread and let melt. Add egg mixture and reduce heat to low, stirring frequently until eggs are thoroughly cooked, around 5 minutes. Sprinkle with salt and pepper and divide between 4 tortillas.
Top each taco with any variety of accompaniments: fresh chile, avocado crema, queso fresco, avocado, and garnish with serrano peppers and cilantro. Serve immediately.
