Rinse and drain the canned chickpeas thoroughly to ensure they crisp up slightly in the pan.
In a medium bowl, whisk together the large eggs, egg whites, salt, pepper, and dried oregano until well combined.
Heat the olive oil in a non-stick skillet over medium heat.
Add the chickpeas to the skillet and sauté for 3 to 4 minutes until they are warm and slightly golden.
Add the spinach to the pan and toss until just wilted, which should take about 1 minute.
Lower the heat to medium-low and pour the egg mixture into the skillet.
Gently stir the eggs with a spatula, pulling from the edges to the center, until soft curds form and the eggs are nearly set.
Sprinkle the crumbled feta cheese over the scramble and fold gently to incorporate.
Remove the skillet from the heat immediately and serve the scramble warm.
