In a mixing bowl, to the sweet potatoes add the salt, chili flakes, dried herbs and half of the olive oil. Give it a good mix so that all of them are well seasoned
Lay this out on a parchment lined baking tray. Bake in a pre-heated oven for 40-45 minutes or until cooked through, at 180°C
In the same mixing bowl, toss the spinach with the remaining olive oil. I have not seasoned these because even the feta is salted and so are the sweet potatoes
When the sweet potatoes are done, remove them and layer over the spinach. Follow this up with the walnuts and the cheese
Serve the roasted sweet potatoes saladwith feta, warm or at room temperature, as is or as a side along with your roasts. Enjoy!
Notes
You can replace the baby spinach with lettuce, rocket leaves, arugula. watercress etc
You can also replace walnuts with pistachios, pine nuts, peanuts etc
You could also replace the Mediterranean dried herbs with any dried herbs/spices of your choice
To make the salad vegan, leave the feta cheese out
