Cut the avocado and remove stone. Take out the flesh and mash it in a bowl.
Peel and finely dice the onion. Throw into the bowl as well.
Chop the tomatoes and chuck in too.
Grate the garlic into the mix and chop the cilantro. Add as well.
Add the salt, pepper and squeeze in the lemon.
If you like it with a bit of kick, lob in a chopped chili too.
Mix well.
Done.
For the tortillas
Using scissors, layer the tortillas on top of each other and cut into triangles (halve, halve, and halve again)
If you want extra crispy tortillas (as Howie does), use a knife to spread some olive oil over them. You can skip this part for slightly softer, more ‘floury’ tortillas (Dave’s favourite).
Sprinkle the salt and cayenne over the tortillas
Place on a tray and bake for 5 minutes in the oven at 200°C/390°F.
