Slice the potatoes in half the long way. Cut each half into 5 to 6 long wedges.
Toss the potato wedges with oil and salt in a bowl.
Cover with waxed paper and microwave for 5 minutes, stirring halfway through.
Preheat grill and grill basket over medium-high heat.
Add potatoes to hot grill and cook stirring every couple of minutes until potatoes are crispy on the outside, about 8 minutes. If you have a hot spot on the grill, just pile the cooked potatoes in a cooler portion of the grill basket.
Serve immediately.
