Cook the rice according to the package instructions. In the last minute of cooking, add the cumin to the rice and stir.
While the rice is cooking, add all falafel ingredients to a food processor and blend on low speed until well combined. Occasionally pause to scrape down the sides of the processor and blend again. There may be a few chunks of onion or chickpeas remaining, this is okay. If the mixture does not form into a ball easily, add 1 tsp water at a time and blend until it does.
Take ~2 tbsp of the falafel mixture and roll into a ball. Flatten into a patty that is about 1/2" thick. Repeat with the remaining falafel mixture.
Cook the falafels, either baking or frying (see below for both options). For a more moist and flavourful falafel, I recommend frying them.
Create your bowl, starting with the rice, veggies and falafels. Top with tzatziki, sesame seeds and your choice of fresh herbs. Enjoy!
