Preheat oven to 400 degrees. Line a baking sheet with foil.
Place the chicken cubes in a small mixing bowl, add the salt, pepper, and BBQ sauce. Toss to coat. Place the chicken in a single layer on the prepared baking sheet and bake for 15 minutes or until the chicken is no longer pink inside. Let cool.
Toss the apples with the lemon juice.
Once the chicken has cooled, thread on small skewers alternating with apple chunks.
If preparing the night before, wrap the skewers in plastic wrap and refrigerate.
Serve with more San-J Asian BBQ Sauce on the side if desired.
