Prepare rice noodles according to package directions. Drain and keep warm. Set aside.
Combine orange juice, arrowroot powder, five-spice powder, red pepper flakes, soy sauce, and honey in a small bowl. Stir to combine and set aside.
Heat olive oil in a large skillet over medium-high heat. Add mushrooms, carrots, onion, and garlic. Cook, stirring frequently, for 3-4 minutes or until carrots and onion soften and develop a bit of color.
Add fresh broccoli to the skillet and cover. Cook, stirring occasionally, for approximately 4-5 minutes or just until broccoli is crisp-tender.
Add orange juice mixture to the skillet and cook for 3-4 minutes, stirring occasionally, or until the sauce thickens and starts to bubble.
Remove from heat and pour vegetables over prepared rice noodles and toss to combine. Serve immediately and enjoy!
