For the hummus and salsa verde, preheat the broiler to high and place the tomatillos, remaining onion, garlic, and jalapenos on a baking sheet lined with parchment paper. Broil on both sides until charred and juicy. Add the salsa verde ingredients with any accumulated juices to the food processor, then pulse, taste, and set aside. Add the refried bean hummus ingredients to the empty food processor, pulse, taste, and set aside.
