Rinse the rice and cook it in 400 ml (1 2/3 cups) of water: bring to a boil over high heat, cover, simmer on low for 15 minutes and rest 5 minutes.
Preheat the oven to 220°C (425°F) with a rack in the upper third. Line a baking sheet with parchment.
Grate the onion and squeeze out the juice. Mix it with the beef, chopped parsley, cumin, smoked paprika, cinnamon and salt, kneading for 1 minute. Shape into 12 logs about 8 cm (3 inches) long.
Bake for 12 to 15 minutes, until browned and 71°C (160°F) in the centre.
Thinly slice the red onion and soak it in the apple cider vinegar for 10 minutes. Mix the Greek yogurt with chopped mint.
Build the bowls with rice, kofta, diced cucumber and tomato, the pickled onion and a spoon of mint yogurt.
