Make pico de gallo: Mix the tomato, red onion, garlic, and cilantro in a bowl. Add hot sauce to taste. Season with salt to taste and set aside until ready to serve.
Heat the oil in a non-stick pan over medium heat. Saute the sausage until it starts to become light golden brown. Add the onion and peppers, and saute until softened.
Add the butter, eggs, and cheese to the pan. Move the eggs using circular motions with a spatula or wooden spoon to fluff them up and cook. Remove the pan from the heat while the eggs are still moist. Season with salt and pepper to taste.
Warm the tortillas on both sides in a nonstick pan over medium heat and set them aside.
Portion the eggs on the tortilla. Fold in the ends and roll tightly.
Serve: Cut in half and enjoy with pico and orange juice. Garnish with jalapeño if using.
