Heat a small non-stick frying pan over medium heat. Add the walnuts and garlic. Turn down the heat and roast until golden by shaking the frying pan. (Be careful not to burn. Garlic is easy to burn.) Transfer to a plate and set aside.
In a medium bowl, add the ingredients for dressing and mix well. Set aside.
Mean while, boil 4 cups of water in a medium pot. When it’s boiling hot, add the beets noodles. Cook for 1 and 15 to 30 minutes by separating the noodles occasionally. Drain and wash the noodles under running water to wash off the excess starch. Drain well.
Transfer the noodles, and the roasted walnuts and garlic into the bowl. Toss to dress.
Place the noodles in the center of the serving plate.
Add the arugula, carrot, orange and the snow peas into the bowl and toss to dress with the remaining dressing.
Place the salad around the noodles.
