Unpack the Arugula and pull out any wilted or bad pieces. Wash it as needed, some packages come pre-washed.
There are a couple ways to toast the Walnuts. First set your oven to 350°F line a baking tray with parchment, spread the walnut out and place in the oven. I hesitate to say how long, lets just say keep an eye on them after 5-6 minutes. The second way is on the stove preferable with a heavy bottom fry pan or cast iron. Don't go anywhere, keep moving the pan so they don't burn on the bottom. Your looking for a nice light brown color in spots, once you see those speed them on a cutting board to cool off. If you were able to find Pickled Beets great, if not make sure to check out my post on how to Pickle Beets. Drain the Beets and if they are whole cut them into halves or even quarters if there are large chunks.
Next cut a Red Onion so you have 1/4 with the skin peeled. I like mine as thin as I can get it for this Salad I find it helps control the sharpness.
Reserve a little of the Beets, Red Onion, Goat Cheese and Walnuts to garnish with at the end.
Place the Arugula, Onion, Walnuts, cranberries and Beets into a mixing bowl. Crumble or tear the Goat Cheese into pieces and spread over the Salad.
