Ingredients
1 onion, chopped
1 tin chopped tomatoes
1 green chilli, chopped (seeds removed if you don't want it really hot)
1 tin black beans, drained but not rinsed
1 tsp each of cayenne pepper/cumin/garlic powder/smoked paprika/coriander/oregano
1 bag of tortilla chips
grated cheese
1 tomato, chopped or some salsa
sour cream
Method
Preheat the oven to 180C. Fry the onion in some oil. Add the drained beans, tomatoes, herbs and spices and half of the chilli. Stir and bring to a boil. Reduce to a simmer and stirring occasionally allow it to cook for about 10 minutes until thickened and the liquid has reduced down and doesn't pool in the bottom of the pan.
Line a baking tray with greaseproof paper. Line with one layer of tortilla chips. Spoon on half the black bean mixture and sprinkle on half the cheese. Do another layer of the same again. Bake for 5-10 minutes until the cheese is melted and the edges of the chips are browning. Remove from the oven and top with sliced chilli, sour cream and tomatoes/salsa.
