Cook all the vegetables together in boiling water until soft.
Drain well (you do not want any water in the mixture) and mash together.
Add the tomato puree, garlic puree, mustard, seasoning, Loprofin Baking Mix and pre-cooked Rice and mix until combined (you may need to add additional Loprofin Baking Mix to ensure the mixture is a mash potato consistency).
Season with salt and pepper.
Divide the mixture into 4 portions and shape into patties.
Heat some oil in a fry pan*. Cook the burgers for 5-6 minutes, turning frequently, until golden and crisp on each side.
Tips
*For a lighter variation, you can also cook the patties on a lightly greased baking tray at 200°C for 15-20 minutes or until browned.
