Start by heating your skillet and washing your vegetables thoroughly. Cut the tomato into slices, and the pepper into 1/2 inch strips. Crack the eggs into a bowl and beat to combine the yolks and egg whites. Coat the skillet with olive oil and place the spinach evenly across the bottom of the pan. Arrange the tomatoes and green pepper slices in an alternating pattern on top of the spinach. Pour the eggs on top of the vegetables so the liquid coats everything evenly. Season with salt and pepper. Cover the eggs until cooked through completely and serve with guacamole on top.
