In a bowl, whisk together soy sauce, honey, ground ginger, red pepper flakes, and minced garlic.
Sprinkle in cornstarch and whisk until fully dissolved and smooth. Set aside.
Heat vegetable oil in a large wok or skillet over medium-high heat.
Add sliced red bell pepper and onion, stirring frequently for 3 to 4 minutes until they begin to soften.
Add broccoli florets and cook for an additional 4 minutes, stirring frequently for even tenderness.
Stir in butter and allow it to melt.
Add shrimp and cook for 2 minutes on each side until opaque.
Pour in the prepared sauce and stir continuously until the sauce thickens and shrimp are fully glazed, about 2 minutes.
Serve immediately, preferably over cooked rice or as desired.
