Preheat your oven to 450ºF. Place the hash browns and frozen veggies on a half sheet pan lined with parchment paper. Drizzle 1 tablespoon of olive oil over the top and season with a pinch of salt and pepper. Toss everything together before going in the heated oven for 20-25 minutes.
While the veggies are in the oven, prepare the remaining components, starting with the chicken. Mix the dried spices and herbs together in a small bowl before sprinkling over the pulled chicken.
Heat a large skillet over medium-high heat with the 1 1/2 tablespoons of olive oil. Make sure the oil is HOT before adding the chicken. Leave the chicken untouched for 1-2 minutes until it's golden brown on the bottom and the seasoning blend is fragrant. Transfer the chicken to a bowl.
Add the skillet back to the stove and reduce to a medium-low heat. Whisk the eggs and egg whites together before going in the pan and cook to scramble. (You may need to use a small amount of butter or oil to cook the eggs, depending on the type of pan you're using.)
Once the hash browns and vegetables are cooked through and browning around the edges, you're ready to assemble the burritos.
Wrap the tortillas in a damp paper towel and microwave for 30-45 seconds to soften before filling to prevent cracking.
Fill each tortilla with the chicken, eggs, veggies, and cheese before wrapping and setting aside. Optionally, you can grill the burritos in a large pan or griddle with cooking spray until golden brown on all sides.
