Make the lemon honey vinaigrette: In a small bowl, whisk together the olive oil, lemon juice, vinegar, garlic, and honey with pinches of salt and pepper. Taste and adjust seasonings.
In a large bowl, toss together the quinoa, strawberries, feta, mint, scallions, walnuts, greens, and sprouts, if using. Pour in the dressing and toss again. Taste and adjust seasonings to your liking. I added a final squeeze of lemon juice and a drizzle of olive oil on top.
This is the kind of salad that gets better as it sits and the flavors mesh together… so if you have the patience, let it chill for 15-20 minutes before serving. Make extra if you want leftovers for lunch the next day.
