In a bowl, lightly mix together meat and beans with a fork until well combined. Mix in onion, garlic, jalapeño, chili powder, salt and pepper. (Be careful not to over-mix or you will end up with a tightly-compacted mixture that tastes unpleasant; it should be light.) Gently form mixture into four 4-inch patties.
Cook burgers on pre-heated grill or ridged grill pan, turning them once, until a meat thermometer inserted in their centers registers 160 degrees (about 8 to 10 minutes). Hot burgers crumble easily, so handle carefully, using a wide spatula.
Serve immediately, preferably on toasted buns, topped with sliced tomato and onion plus some well-drained salsa.
