For an extra layer of flavor, consider grilling the pineapple chunks before using them as a garnish. The caramelization will add a delightful sweetness. If you prefer a spicier slaw, add a pinch of red pepper flakes to the dressing. Feel free to substitute ground turkey or chicken for the ground beef, adjusting cooking times as needed. Sliders can be assembled ahead of time and reheated gently in the oven or microwave. However, the slaw is best added just before serving to maintain its crispness.
