Crack the eggs into a bowl and whisk with 1 tablespoon of water until smooth and fluffy. Set aside.
Heat olive oil in a skillet over medium heat. Add diced jalapeno, garlic, and red onion. Sauté for 2–3 minutes until softened and fragrant.
Whisk the eggs again, then pour them into the skillet with the vegetables. Gently scramble until the eggs are fully cooked but still soft.
Warm the flour tortillas slightly for easier wrapping.
Divide the scrambled egg mixture evenly among the tortillas. Top each with salsa and sliced avocado.
Fold in the sides and roll tightly into an Egg and Avocado Breakfast Burrito. Serve immediately while warm.
