To make hummus put 1 can of chickpeas, juice from 2 limes, and 2 tablespoons tahini in a food processor. Add water slowly — just enough to make your chickpeas smooth. Add salt.
Put the hummus in a bowl and hand mix in 1/2 cup breadcrumbs. Add spices, if you want any. The goal is to make a solid, thick burger. The more water you use, the more breadcrumbs will be needed to thicken it. 1/2 cup is a good start, but add more if it’s mushy. Now divide the mix into 3 or 4 patties.
Spray oil on a plate grill (don’t spray oil if you’re cooking over a flame grill) and cook for about 10 minutes on high. Put burgers on buns and garnish.
Slice the sweet potatoes and place on the oiled plate grill. Spray more oil on top and sprinkle with salt. Grill on high for 10 minutes and serve with the burgers.
Enjoy!
