• 4 large sweet potatoes
• olive oil
• salt

Scrub the potatoes and pat dry. Cut them into strips and put them on a parchment paper covered baking tray. Drizzle with olive oil and sprinkle with salt. Put the tray on the top shelf in the heated oven and bake for 25 minutes. Move the tray to the bottom shelf and put the black bean burgers on top and bake an additional 20 minutes. Don’t forget to flip the burgers when there is ten minutes left.
