Toss 8 thinly sliced strawberries, 10 cups baby arugula and 4 ounces crumbled Parmesan in a large bowl. For the vinaigrette, whisk 1 tablespoon each Dijon mustard and sugar, 2 tablespoons fresh lime juice and 1/4 cup fresh orange juice. Add 1/4 cup olive oil in a thin stream while whisking. Taste and season with salt and pepper. Toss the salad with some of the dressing and serve the rest on the side.
