Cook your brown rice – I used the Instant Pot to speed things up. Preheat the oven to 400º and line a baking sheet with parchment.

Food process your sunflower seeds until they're coarsely ground (see photo below). Remove from food processor and set aside. Grate your carrots.

In the food processor, combine pulsed sunflower seeds, grated carrots, and remaining ingredients. Pulse until fully combined. If the mixture is a bit dry/crumbly, add a quick drizzle of olive oil to help bind it together. 

Use your hands to shape the mixture into patties – it should make about 6 - 3 inch burgers.

Bake the veggie burgers for 18-20 minutes, flipping once at the halfway point. Remove from oven and allow to cool.
