Wash and drain the rice.
Boil 6 cups of water with 2 tbsp salt. When boiling add in the rice and boil for 6-8 minutes until half-cooked. The rice should still be slightly firm in the middle (like pasta is al-dente). About 4 minutes in, add the broken reshteh noodles and boil them together.
After 6-8 minutes, wash immediately with cold running water to stop the cooking process.
Add 3 tbsp oil to the bottom of a large pot. For a bread tahdig, line with lavash bread, covering the bottom of the pot.
Add in a quarter of the half-cooked rice and noodle mixture, sprinkle with a few dashes of cinnamon (about ½ tsp), and mix gently with a fork. Repeat the process until the rice is used up.
Create a mound shape with rice by dragging up the sides, and poke 5 holes into the mound with the back of a spoon. With a slotted spoon, pour over 3-4 tbsp of vegetable oil.
Leave it on medium heat for 10 minutes, allowing the steam to begin to rise. Then turn it to the lowest setting, put on the lid wrapped in a dishcloth (to collect steam droplets), and leave to steam for another 35 minutes.
Meanwhile, let’s make the meatballs. To make the meatballs, add in all the ingredients: the cooled and cooked quinoa, cooked black beans, oats, onion, and spices into a food processor. Adjust the salt to your taste.
Take small amounts of the mixture and roll them into meatball shapes. If they are too sticky, apply a bit of oil to your hands when rolling. Or, add a little bit of cornstarch to the mixture, 1 tbsp at a time.
Around 10 minutes before you would like to serve, fry the ‘meat’balls in 2-3 tbsp of oil on medium heat until nicely browned on all sides, and set aside on a paper towel to absorb excess oil.
At the same time, caramelize the sliced onion with 3 tbsp oil on low-medium heat for 5-10 minutes.
Heat the dates and raisins in a pan with a little water or oil for 2-3 minutes.
When the rice is ready, dissolve the ground saffron with 3 tablespoons of boiling water. Add in the butter, and 2 spatulas of cooked rice. Mix evenly and use this saffron rice for garnish.
Assemble the rice and 'meat'balls', along with the raisins, dates, and caramelized onions. Enjoy with tart vegan yogurt and nush-e-jan!
