This is a nice simple salsa you can eat with corn chips on its own, or use as the sauce for enchiladas, Mexican rice etc.
1 x 400g can tomatoes
½ onion (don’t bother chopping up the blender will take care of that)
2 garlic cloves
2-3 Tbsp cider vinegar
Large pinch each of oregano, cumin, sugar, salt.
A handful of fresh coriander (optional, but definitely adds to the flavour)
Whiz together in a blender.
