Vegan rainbow burger

You can grill a rainbow, grill a rainbow, grill a rainbow too.

Prep time15min
Cook time5min
Total time20min


  • 1 medium red onion, peeled and roughly chopped
  • 1 medium yellow pepper, diced
  • 1 cup whole kernel corn
  • 2 spring onion stalks, chopped
  • ½ large baby marrow, grated
  • 1 can (425g) chickpeas
  • 1 large tomato, chopped into quarters
  • 1 small avocado, skin removed
  • ½ tablespoon garlic powder
  • ½ tablespoon dried Italian herbs
  • 1 teaspoon ground paprika
  • Salt and pepper, to taste
  • 130-200g oat flour
  • Coconut oil, for grilling


  1. In a large bowl, combine the red onion, yellow pepper, corn, onion and baby marrow. Mix well and set aside.
  2. Add the chickpeas, tomato, avocado, and herbs into a high-speed food processor. Pulse until smooth and blended thoroughly.
  3. Pour the mixture into the vegetables and mix until well combined.
  4. Slowly start adding the oat flour, around 65g at a time, until the mixture holds its shape when moulded into round patties.
  5. When you’re happy with the mixture’s consistency, mould 4-6 patties (depending on what size you prefer). Place to the side.
  6. Heat the grill and brush with coconut oil. Make sure there’s enough to ensure your patties don’t stick.
  7. Place the patties on the grill and close the lid. Cook for 3-5 minutes, or until well browned on the underside. Reduce the heat if they are browning too quickly.
  8. Once cooked, flip the patties gently and cook on the other side for another 3-5 minutes.
  9. Remove the patties from the grill and let them cool slightly.
  10. Serve your rainbow burgers with your favourite buns, dressings and sides.

Recipe Notes

Don’t have oat flour? Make it! Grind 2 cups of old-fashioned oats in a food processor and blend until it resembles a fine, flour-like powder. Easy does it. Vegan homemade patties won’t be as firm as meat ones, so be sure to flip them slowly so that they keep their shape and don’t fall apart. Want ideas for burger toppings? Try adding shredded cabbage, avocado slices, leafy greens, caramelized onions and spicy mayo for a healthy, flavorsome kick!
