Cut the bacon into 4 cm long pieces. Clean the spring onions, cut the white and light green diagonally into thin rings. Whisk eggs and cream together, season with salt and pepper.
Fry the bacon in a non-fat frying pan until crispy, drain on kitchen paper. Sauté 2/3 of the spring onions in the pan in the bacon fat and oil for half a minute. Pour the egg cream over the spring onions in the pan. Use a spatula to slide along the bottom of the pan approx. 3 to 4 times to the center of the pan over mild heat. Cover and let stand for 1 to 2 minutes. Cover the omelette with the pieces of bacon, fold it up and serve sprinkled with the remaining spring onions.
