Combine chicken, pork, jalapeno peppers, cilantro, garlic, and soy sauce in a bowl. Mix well and form into 12 small patties. Place on a platter and brush with olive oil. Sprinkle with salt and pepper.
Preheat an outdoor grill for high heat and lightly oil the grate.
Place patties on the grill and cook, covered, until browned, 3 to 4 minutes per side. Do not press down. Place patties inside slider buns.
Mix ranch dressing, mayonnaise, and salsa together to make spicy ranch dressing. Serve alongside sliders.
