Mix honey with Worcestershire sauce, apple cider vinegar, garlic, salt, pepper, onion, ginger and red pepper. Whisk until well combined.
Reserve half of the sauce and pour the other half over the shrimp and mix to combine. Cover and refrigerate the shrimp about 20 minutes.
Prepare a grill fire with pecan or hickory chunks to about 325°, using a low fire will keep the honey from burning.
Place sliced bell peppers onto a grill pan and cook about 5 minutes with the grill closed.
Move the peppers to the side and add the shrimp in a single layer.
Cook with the grill closed about 5 minutes.
Flip the shrimp and continue to cook another 5- 6 minutes until shrimp reaches about 140° with a digital thermometer.
Remove shrimp and peppers to a pan.
Dice the peppers and set aside.
Add reserved sauce to a large skillet and place over medium heat.
As the sauce starts to bubble, add the shrimp and diced peppers and stir to coat.
Mix in the cooked and drained spaghetti, tossing until well combined and the spaghetti is coated in the sauce.
Garnish with parsley and serve immediately.
