Preheat oven to 400º F. Line a baking sheet with parchment paper or a silicone mat.
Chop off the greens and roots of the radishes and rinse and scrub them thoroughly.
In a small bowl, toss the radishes with 1 tablespoon of olive oil, the garlic powder, and a dash of salt.
Spread the radishes on the baking sheet and bake for about 15 to 20 minutes.
While the radishes are roasting, prepare the zucchini noodles. Rinse and chop off both ends of the zucchini. Using Blade B, spiralize the zucchini.
Heat the remaining olive oil in a sauté pan over medium-high heat. Sauté the onions until they start to turn translucent. Add the minced garlic and cook for another minute.
Bring the heat down to medium and mix in the zucchini noodles and orange peppers. Cook for about 5 minutes. Toss in the chopped sage and basil and season with salt and pepper. Remove the noodles from heat. Plate them in small bowls.
Once the radishes are browned, remove them from the oven. Top the zucchini noodles with the roasted radishes.
