Wash and grate the beetroot.
Place a pan on medium heat and add the oil to it.
Once hot, add the grated beetroot and cook down till most of the water evaporates and the beetroot is cooked. This should take about 3-4 minutes.* Set aside.
Once the beetroot has cooled down add it to a large bowl along with the mint, black beans, cooked millet salt, pepper and cumin and mix well.
Let the mixture sit in the fridge for about 1 hour.
Divide the mixture into four and shape into patties.
Turn your tandoor on and allow it to heat up.
Lightly brush the tandoor with some oil and place two patties onto it.
Cook for 7-10 minutes until the patties are done.
Repeat with the other two patties.
Assemble the burgers with the hummus, lettuce, red onions, burger buns and beetroot patties.
Serve with fries and enjoy!
