Steam/roast the beetroots and boil the potatoes. Peel when done and keep them aside.
In a pan, on low flame, lightly toast 1/2 cup instant/ rolled oats until they become fragrant and light brown. Cool and coarsely ground.
In a mixing bowl, grate the 2 medium boiled potatoes and 2 medium steamed beetroots, 1 tbsp grated ginger, a handful of finely chopped cilantro/ fresh coriander leaves, 1-2 finely chopped green chillies (optional), 1/2 cup coarsely powdered toasted oats, 1 tsp roasted cumin powder, 1/2 tsp paprika/ red chilli powder, 1/2 tsp lime juice and salt to taste.
Mix well with gentle hands so that everything gets uniformly mixed.
Divide this mixture into equal portions. Oil your palms slightly, shape the portions into spheres and flatten them a bit into kebab/ tikki shapes.
You may also (optional) coat them with toasted oats on both sides before pan-frying
Heat a pan (I used cast iron) and spread 1-2 tbsp oil. Pan fry till light golden brown on both sides and serve hot with a chutney/ sauce of your choice.
