Slice 20 g red onion finely, crumble 40 g feta cheese, chop 8 sundried tomatoes, and roughly tear 40 g baby spinach.
Add the spinach, 40 g arugula, red onions, sundried tomatoes, and feta cheese to a large bowl. Pour over 2 tablespoons sundried tomato dressing and toss to coat. Top with 80 g croutons.
Notes
This salad tastes best served cold, so refrigerated ingredients are preferable.
