Preheat oven to 350° and line a baking dish with parchment paper. Also grab a large mixing bowl, and your food processor.
Add the red pepper and onion to the food processor, and pulse until minced. Pour into the large mixing bowl.
Add the brazil nuts, seeds, garlic cloves, chili powder, cumin, and sea salt to the food processor, and blend until it has combined into a grainy mixture. Pour into the mixing bowl with the onion and pepper.
Add the beans and cilantro to the processor, and blend until almost smooth (a few chunks of bean is okay). Pour into the mixing bowl.
Pour your oats into the mixing bowl with the other ingredients, and stir well to combine. The oats will expand and help hold the burgers together.
Form into tight palm-sized patties, and place each onto the baking sheet.
Bake for 25 minutes.
Remove from the oven and use a spatula to flip each burger. Continue baking for another 10 minutes.
Serve with ciabatta, avocado, cucumber, and arugula.
