Heat avocado oil in a non-stick skillet over medium heat.
Add ground pork chorizo and cook until browned and crispy, breaking it up with a spatula as it cooks.
In a small bowl, whisk together the large egg, liquid egg whites, sea salt, and black pepper.
Pour the egg mixture into the skillet with the chorizo, stirring gently to scramble until the eggs are just set.
Toss in the fresh baby spinach and stir for 30 seconds until the leaves are slightly wilted.
Warm the whole wheat tortilla in a separate dry pan or over a low flame for 30 seconds until soft and pliable.
Place the egg and chorizo scramble in the center of the tortilla, then top with sliced avocado and fresh pico de gallo.
Fold in the sides of the tortilla and roll it up tightly.
Place the burrito back in the skillet seam-side down for 1 minute to seal the edge and create a golden, crispy exterior.
