*Replace milk with soy milk for lactose-intolerant people. Note that the entire recipe only calls for 1 cup of milk, even though the amount of milk/soy milk adds up to more. If making 75% with dairy and 25% without dairy, use .75 cup milk and .25 cup soy milk.

Chop onions and garlic. Beat egg with a fork. Combine all ingredients in large bowl. Mash black beans and mix everything with your hands. Form veggie balls, diameter approx 1” or a golfball-sized.
Heat large nonstick skillet over medium heat. Spray with nonstick spray. Transfer veggie balls to skillet (may need to do this in batches); cook 6 to 8 minutes while turning occasionally, until browned and warmed through on all sides.

When done, transfer immediately to a platter lined with paper towels.
