Add peppers, onions, salt, and pepper. Cook for a few minutes, until softened to your liking.
Meanwhile, scramble the eggs in a medium bowl.
Reduce heat to medium-low. Pour eggs into the skillet and cook, pulling to the center with a silicone spatula as the set underneath, until just cooked through.
Divide between two plates and top with cheese, cilantro, and hot sauce to taste.

Notes
Cotija cheese is a crumbly white cheese made primarily from cow's milk. It's available in a lot of big supermarkets in the U.S., but if you can't find it, there are plenty of other options that will work beautifully. To keep with the Mexican-inspire vibe, try queso fresco or queso ranchero. Or can substitute a basic cow's milk feta, or even shredded jack, pepper jack, or extra-sharp cheddar.
As with most scrambled egg recipes, this one takes mere moments to make and is at its best shortly after cooking. I don't recommend making it in advance.
That said, leftovers keep well in an airtight container in the fridge for a week. Reheat with a short spin in the microwave or a frying pan.
