Preheat the oven to 425 degrees and grease a 12-muffin tin.
Place the ground turkey in a large mixing bowl.
Place the onion, celery and pepper in the food processor. (I have a mini chopper I like to use for this.) Pulse until finely chopped, and then add to the ground turkey.
Add the egg, oats, and steak seasoning to the bowl.
In a small bowl, mix together the barbecue sauce, salsa, and Worcestershire sauce. Pour half the sauce mixture into the bowl with the turkey and fully incorporate. (I find it easiest to use my hands.)
Using an ice cream scoop, fill the muffin tins and top each loaf with the remaining sauce.
Bake for 20 minutes or until cooked through and slightly browned on top.
