Heat the olive oil in a skillet over a medium heat. Slice the zucchini into half-inch thick discs. Add the zucchini to the skillet in an even layer. Cook for 2 minutes on each side until just tender and lightly golden.
Step 2
Crack the eggs into a mixing bowl. Add the grated parmesan, mozzarella, oregano, salt and pepper. Beat well to combine.
Step 3
Pour the beaten egg and cheese mixture over the tender zucchini. Allow the egg to settle and start cooking. Once the egg begins to set around the edges, use a spatula to ease the omelet away from the side of the skillet, allowing any uncooked egg to flow underneath. Cook until set on top and no liquid remains. Serve with your favorite Keto sides.
