Heat the oil in a large nonstick skillet over medium-high heat. Add in the roast beef, stir once and let the meat brown, about 2 minutes, and stir again. Add in the BBQ sauce and simmer for 5 minutes.
Layer the shredded cheese on top of some tortilla chips on a large platter. Pour the piping hot meat over the cheese and then top with the crispy onions, cherry peppers and dollops of the Honey Horseradish Crema.
Mix the sour cream, horseradish, honey, mustard and salt in a bowl. Let the crema sit for 20 minutes before serving.
