Wash the peaches and remove their pits. Cut into wedges. Over a medium heat, preferably a grill pan, cook the wedges for 2-3 minutes until lightly caramelized and grill marks appear.
Meanwhile, peel the cucumber and cut it into slices. Pit the avocado and dice it.
Wash the green onion and cherry tomatoes. Cut the green onion into thin rings and halve the cherry tomatoes.
Wash the arugula and spinach, spin them both dry.
Coarsely chop the pumpkin seeds. Without any oil, toast the seed in a pan until they are lightly browned and fragrant.
For the vinaigrette, combine olive oil, vinegar, lime juice, maple syrup, and mustard. Season with salt and pepper to taste.
Place all prepared ingredients in a large bowl and pour the vinaigrette over them. Stir everything well.
Serve the salad on plates topped with the peach wedges and crumbled feta.
