Prepare mashed sweet potato by roasting 1 small potato at 400 degrees F for about 1 hour or until soft.
Finely dice peppers using a food processor.
Add peppers and olive oil to a non-stick skillet and sauté until soft (about 5 minutes).
Turn off heat and add corn. Stir until combined. Set aside to cool.
Place sweet potato and half of the beans (about ¾ cup) to the food processor fitted with the “S” blade.
Process for about 15 second or until combined.
Add oats and spices and process until combined.
Transfer processed mixture to a medium bowl.
Add cooled veggies and the other half of the beans and mix well. Taste and adjust seasonings if needed.
Grease two large baking sheets.
Measure out ¼ cup of the mixture and form into a patty on the prepared baking sheet.
Repeat until all of the mixture is used, spacing about 1-2” apart (leaving room for flipping).
Bake at 400 degrees F. for 20 minutes.
After 20 minutes, spray the side facing up with cooking spray or spray oil. Very carefully flip and continue baking 15-20 minutes longer or until both sides are browned.
Remove from oven, let cool slightly and serve.
To freeze: let patties cool to room temperature, then place them in a single layer on a greased baking pan (or one lined with wax paper). Once they are completely frozen, transfer to a ziploc bag or airtight container. To reheat: Place in a warm oven (350 digress F) for about 10 minutes or until heated through. You can also microwave on high for 1 minute but the burgers will not retain their crispness if done this way.
