Grilled Potato Salad

Cook potatoes and sweet potatoes in a pot of gently boiling water until tender. Drain and set aside.

Combine mayonnaise, mustard, garlic powder, onion powder, and cayenne pepper in a large bowl. Season with salt and pepper. Mix in potatoes, gently coating them with the mayonnaise mixture. Be careful not to break the potatoes.

Grill potatoes on a preheated grill until slightly charred. Set aside and keep warm.

Make the dressing: Cook bacon in a skillet until crispy and renders 2 tablespoons of fat. Set bacon aside and transfer bacon fat to a bowl. Whisk olive oil, vinegar, parsley, and spring onion into the bacon fat. Season with salt and pepper.

Coat the grilled potatoes with the dressing and top with crispy bacon bits.
