Place the aluminum-wrapped beets on a baking tray before roasting them in the oven for a time between 45 minutes to 60 minutes until they turn fork-tender.
The oven roasted beets require a couple of minutes of cooling time before you proceed to the next step.
Trim the beet skin then cut the pieces into small pieces for the salad.
A large mixing bowl serves as a receptacle to unite arugula and roasted beets within it.
Feta cheese crumbles should be added according to personal preference on top of the salad.
Store the olive oil with balsamic vinegar together with salt and pepper in a small bowl while stirring to create a dressing.
Toss the salad carefully after dressing it evenly with the dressing mixture.
The walnuts require rough chopping before you add them on top of the finished dish.
