Preheat the oven to 425 degrees F. Place the broccoli on a baking sheet and drizzle with the oil. Sprinkle with the salt, pepper and crushed pepper flakes. Roast for 15 to 20 minutes, until slightly charred.
While the broccoli is roasting, bring a pot of salted water to a boil to cook the noodles.
In a large skillet or saucepan, make the sauce. Heat the sesame oil over medium-low heat. Add in the garlic and ginger and cook for a 1 minutes. Stir in the peanut butter, soy sauce, water, chili garlic sauce, lime juice and honey. Stir until combined and smooth.
Cook the noodles according to the directions (if using ramen noodles, it’s about 3 minutes!) Drain the noodles well.
Add the noodles to the sauce and toss. Toss in the red peppers, green onions, peanuts and cilantro. Add in the roasted broccoli. Toss everything well, until it’s combined. Serve immediately.
