Meanwhile, in a large skillet, heat the oil over medium-high heat until hot. Add the onion, pepper, and a pinch of salt. Cook, stirring occasionally, until the onions are translucent, about 3 minutes. Add the garlic and chili powder and cook, stirring, for 1 minute. Stir in the tomatoes and beans. Simmer until the chicken is ready.
Divide the chicken strips among the hot dog buns. Top with the chili and garnish with red onion.
