Preparation Preheat broiler. Whisk eggs and cream in large bowl to blend. Stir in feta cheese, tomatoes, onions, basil, salt, and pepper. Melt butter in large ovenproof nonstick skillet over medium-high heat. Add egg mixture; do not stir. Cook until eggs start to firm and sides and bottom begin to brown, lifting sides occasionally to let uncooked egg run underneath, about 5 minutes. Sprinkle with olives and Parmesan cheese. Transfer skillet to broiler and cook until eggs start to puff and brown, about 2 minutes. Using flexible spatula, loosen edges and bottom of frittata. Slide out onto plate. Slice frittata into wedges. Serve warm or at room temperature.
