Take a baking dish. Mix the cream cheese and sour cream, spread the bottom layer into the baking dish (approx. 1 cm high). Chop the spring onions, mix with the salsa, add to the baking dish as a second layer. Scatter grated cheese on top as a 3rd layer. Finished!
Use nachochips like small scoops, with plenty of them, so that you get something from all three layers. Is addicting !!!
