Preheat the broiler. Heat oil in a non-stick 9″ skillet. Break eggs into a bowl, mix with salt and red pepper flakes until just blended. Toss in Mann’s Broccolini® and garlic, cook about 1 minute over medium-high heat until Broccolini turns bright green. Reduce heat to medium and spread Broccolini in an even layer.
Pour in eggs and cook, lifting edges as they firm up to let the uncooked egg flow under, until the underside is fully set (lift with a spatula to check). Shake pan now and then, to make sure frittata is loose. Sprinkle with cheese and place under broiler 1-2 minutes until the top is very lightly browned. Cut into wedges. Serve hot or cold.
