In a medium bowl, whisk together the egg whites, cottage cheese, sea salt, and black pepper until the mixture is well combined and slightly frothy.
Heat the avocado oil in a non-stick skillet over medium-low heat.
Add the cherry tomatoes to the skillet and sauté for 2 minutes until the skins begin to soften.
Add the baby spinach to the pan and toss until just wilted, which should take about 1 minute.
Pour the egg white and cottage cheese mixture into the skillet over the vegetables.
Using a silicone spatula, gently push the eggs from the edges toward the center, allowing the uncooked liquid to flow underneath.
Continue cooking slowly over medium-low heat until the eggs are set but still moist and creamy.
While the eggs finish, toast the sprouted grain bread and top it with the sliced avocado.
Plate the fluffy scramble next to the avocado toast and garnish with fresh chopped chives.
