In a small bowl, whisk together olive oil, fresh lime juice, honey, salt, and black pepper until well combined.

Slice the grapefruit and oranges, carefully removing the skin and pith, then slice into approximately 1/4-inch rounds.

On a serving platter, arrange a layer of fresh arugula as a base.

Layer the sliced citrus fruits and red onions over the arugula.

Drizzle the dressing evenly over the salad.

Sprinkle with roasted pistachios and fresh herbs before serving.
