Prepare a medium-high gas or charcoal grill fire or heat a grill pan over medium-high heat.
In a small bowl, combine the lime juice, honey, cilantro, Serrano, and a pinch of salt. Gradually whisk in the 1/4 cup of oil.
Toss the scallions with the remaining 1 Tbs. of oil and 1/2 tsp. salt. Grill the scallions until tender and lightly charred all over, 4 to 6 minutes. Cool slightly, then slice into 1/2-inch pieces.
In a large bowl toss the greens with enough vinaigrette to lightly coat. Add the scallions, mango, and peanuts. Toss and serve.
