Salsa: Combine all the ingredients in a bowl and let sit at room temperature for at least 30 minutes before serving.
Sausage tacos: Combine the preserves, jalapeno and lime juice in a food processor and process until smooth. Season with salt and pepper, to taste.
Heat a grill to high. Brush the links with oil and season with salt and pepper, to taste. Grill until lightly golden brown. Cut the sausage in half lengthwise and brush the apricot glaze mixture on both sides. Grill until dark golden brown, then remove to a cutting board and slice.
Grill the tortillas quickly on each side just to heat through, about 5 seconds per side. Fill with some of the hot and sweet sausage and top with some of the cheese and some of the salsa.
