Directions

1. Drain beans in a strainer and rinse with cold water. Pour beans onto a plate and thoroughly pat dry with paper towels to remove all excess moisture. Set aside.
2. Put walnuts and oats in a food processor and whirl until well chopped.
3. Coarsely chop green onions with a knife and add them to the processor along with maple syrup, 1 tsp. chipotle chilies, the cumin, and salt. Add black beans and pulse until everything comes together, 10-12 one-second pulses (you will still see a few whole black beans in the mix, which will add texture). Taste and stir in a little more chipotle chili if you’d like spicier burgers.
