Make The Lexi’s Signature Vegan Activated Charcoal Burger

Lexi Monzeglio, chef and co-owner of Lexi’s Healthy Eatery – which has a branch at the Flamingo Shopping Centre in Modderfontein – shares the recipe for their signature Activated Charcoal Burger.

Burger patty ingredients:
– 500g sweet potatoes.
– 400g canned chickpeas (you can also substitute with butter beans if you don’t have chickpeas).
– 1 large onion.
– Pinch of nutmeg.
– Pinch of white pepper.
– Salt, pepper and lemon juice (bottled or fresh lemon).
– 1 cup oat flour, quinoa flour or normal flour if you cannot find the other flours.
– 1 to 2 tbsp activated charcoal.

Carrot hummus ingredients:
– 1 can chickpeas.
– 1-2 cups roasted carrots.
– 1/2 teaspoons cumin.
– 1/2 teaspoon salt.
– 2 tablespoons olive oil.
– 1/4 cup water.
– 3 tablespoons tahini.
– Juice of one lemon or 2 tablespoons of lemon juice.


  1. Oven roast the sweet potatoes with the onions at 220°C until they are charring and cooked through.
  2. In a separate tray (if you are doing the carrot hummus) oven roast the carrots until also charred and cooked through.
  3. Keep the oven on 220° to bake the patties later.
  4. It’s best to use a food processor to blend the sweet potatoes, onions, chickpeas and the rest of the burger patty ingredients, but if you don’t have a food processor you can pulse it in a blender, OR use a potato masher and really mash it all up by hand. You will need to use a knife to finely chop the onion after roasting if you don’t have a blender just to ensure it incorporates nicely.
  5. Measure out about half a tennis ball size of the patty mix, or 120g. Place the patties on a lined, greased baking tray and bake for about 15- 20 minutes. When they are done, take them out and put them straight into the freezer to cool down as quickly as possible. This is the MOST important part of making good veggie patties.
  6. While the patties are baking and cooling, you can prepare the carrot hummus. Blend all the hummus ingredients together until combined but quite chunky.
  7. Once the patties are cooled, get a pan and set a nice amount of oil on medium heat. Pan-fry the patties in the oil (you can also deep-fry them if you want a crispy patty, but obviously that is the less healthy option). Construct your burgers with whatever you have in your fridge and bon appetit.
