Step 1

Tip tortilla chips on to a baking tray, pour over salsa and scatter over a few sliced spring onions.

Step 2

Grate over a good chunk of cheese (fontina is perfect, but cheddar will do). Add a pinch of crushed chilli flakes, then put under a hot grill for about 3 minutes to melt the cheese. Serve with soured cream or guacamole (optional).
