Start by cooking the vegetables.
Plunge the chopped peas and flat beans into a saucepan of boiling salted water for 5 to 8 minutes. Then immediately cool them in cold water to preserve their bright green color.
Prepare the vinaigrette. In a bowl, mix the lime juice, olive oil, honey, and mustard. Season with salt and pepper to taste.
In a large bowl, combine the quinoa with the green vegetables, sliced red onion, fresh herbs, and sprouts. Crumble the feta generously over the top, then drizzle with the lime vinaigrette.
Serve chilled and add a few seeds!
