Crack the eggs into a medium bowl.
Add 1 tablespoon of water and whisk thoroughly until smooth and slightly frothy.
Heat olive oil in a large skillet over medium heat.
Add diced jalapeño, garlic, and red onion.
Sauté for 2–3 minutes until softened and fragrant.
Whisk the eggs one more time and pour them into the skillet.
Stir gently as the eggs cook, creating soft and fluffy scrambled eggs.
Remove from heat when the eggs are just set.
Warm the flour tortillas slightly to make them easier to fold.
Divide the scrambled egg mixture evenly among the tortillas.
Top each tortilla with salsa and sliced avocado.
Fold in the sides and roll tightly into a burrito.
Serve immediately while warm.
