15 minutes
30 minutes


  • 4 brown onion peeled, thinly sliced
  • 2 tbsp olive oil
  • 2 tbsp brown sugar
  • 1 sachet fajita seasoning
  • 8 wholegrain tortillas
  • 800 g black beans (2 x 400g can), rinsed, drained
  • 2 fresh sweetcorn cob kernels removed
  • 375 g mild thick and chunky salsa
  • 2 cups reduced fat tasty cheese grated
  • olive oil spray
  • 1 avocado smashed, to serve
  • 1 lime cut in wedges, to serve
  • sour cream to serve
  • fresh coriander (cilantro) to serve


  • ½ brown onion peeled, finely chopped
  • 2 tomato vine-ripened, deseeded, finely chopped
  • ½ lime juiced


  • Preheat oven to 220°C fan forced. Lightly grease two large oven trays.
  • Place onions in a shallow microwave-safe dish. Cover with damp paper towel. Microwave on High/100% power for 4 minutes until soft.
  • Heat half the oil in a medium, non-stick frying pan over a medium heat. Add onions and sugar. Cook, stirring occasionally, for 15 minutes or until caramelized. Add seasoning. Cook, stirring for a further 1 minute.
  • Divide onions evenly over half of each tortilla. Top with beans and corn. Spoon over salsa and sprinkle with cheese. Fold over to enclose.
  • Place tortillas onto trays. Spray both sides lightly with cooking oil. Bake for 10 minutes, or until cheese is melted and tortillas are golden around the edges.
  • Meanwhile, make salsa. Combine all ingredients in a bowl. Serve tacos with salsa, avocado, lime wedges, sour cream and coriander leaves.

Tip: Serve tacos with chipotle mayonnaise instead of sour cream. For a spicy kick, add drained pickled jalapenos to the salsa.

    Tip: For a non-vegetarian option, replace 1 can of black beans with 300g chopped cooked chicken.

      Tip: These are a great after-school snack. Make to the end of step 3 and place on a tray in the fridge. Kids can cook them between baking paper in a sandwich press.
