- Preheat frittata pan over medium heat. In a medium bowl, mix egg whites until frothy. Add cherry tomatoes, spinach, broccoli, garlic, 2 Tbsp basil, Parmesan, salt and pepper.
- Add the egg mixture to the frittata pan and cook for 3-4 minutes until the egg whites begin to set around the edges. Loosen egg white with a rubber spatula. Flip pan and cook for an additional 3-4 minutes until frittata has set and is cooked through.
- Transfer from the pan to a plate and sprinkle with the remaining 1 Tbsp basil. Slice the frittata into thin wedges and eat warm or at room temperature with dollops of sour cream on top.
