Preheat the oven as 180 degrees. Place the beetroot as slice onto the baking sheet, drizzle a few drops of olive oil and roast for about 15 minutes at 180 degrees. Remove from the oven and set aside to cool.

Place the roasted beets in a food processor and blend it as a mixture.

Transfer the beets into a large bowl, add boil and mashed beans--, chopped garlic, soya sauce, vinegar, brown rice flour and salt as your taste and stir to combine. If the texture is too mushy add more rice flour until you obtain the desired consistency.

Using my hands, shape the burgers and wrap both side sesame seeds and place them on a lined baking sheet. Bake in the oven for 10 minutes on one side, then flip over and bake for 10 more minutes at 180 degree and Serve it hot.
