If you haven't tried snow or snap peas on the grill, you should - they're great, and they're quick. Here they are excellent with shiitakes and scallions grilled alongside in an Asian marinade. You'll need a grill basket for this recipe.
2 cups shiitake mushroom caps in bite-sized chunks
3 cups snow peas, stemmed
Up to 1 bunch scallions, cut into 1 1/2- 2-inch lengths
1 Tbsp soy sauce
1 Tbsp sesame oil
Combine all ingredients in a large bowl and toss to coat. Let marinate for up to an hour if you have time; even a few minutes is good.
Heat the grill and place the vegetables into the grill basket. Grill over high heat, stirring occasionally, for 6-10 minutes, until nicely browned in places. Serve hot.
