Heat the olive oil in a large skillet over medium-high heat. Add the arugula, spinach and rainbow chard to the hot pan. Cook down the greens for about 2 to 3 minutes, or until tender. Add the spring garlic and cook for another minute. Crack the eggs over top and cover. Cook the eggs until the whites are set, about 15 minutes. Adjust seasoning, garnish with a lemon wedge, and serve with toast.
