Coat a nonstick skillet with nonstick spray, pour eggs into skillet over medium-low heat and cook, scraping long ribbons through the pan with a rubber spatula, until large curds begin to form but eggs are still wet.

Toast tortillas over low heat on stovetop until warmed through and slightly charred on each side.

Spread 1 tablespoon hummus on each tortilla then divide tomato mixture, egg mixture, and sliced avocado between tortillas. Sprinkle cilantro and hot sauce (if using) over eggs then roll each tortilla into a burrito by first folding the bottom side up and over the filling, then folding the side in and rolling tightly, ending seam-side down.
