Slice the peppers and place in a pint canning jar. Add the vinegar, water, honey, pepper, and salt to a small saucepan and bring to a low boil. Whisk, remove from the heat, and pour over the peppers in the jar. Allow to sit at room temperature for an hour. You can do this beforehand and refrigerate until you're ready to use.
For the sliders
Split the Hawaiian rolls like a bun, but leave them connected at the bottom. Brush or pour 3 tablespoons of butter on the insides of the bun. Bake at 375℉ for 7 minutes.
Heat skillet or grill to medium-high and cook sausage on all sides. Remove the sausage from the skillet. Add 1 tablespoon butter and a splash of white wine vinegar to the skillet. Whisk to remove the browned bits off the bottom. Split the sausage 3/4s through but leave connected. Now cut each sausage into 4 equal parts.
Place one sausage in each Hawaiian roll with the cut part of sausage up. Pour the butter from the pan, honey, and bbq seasoning over the sausage. (You may have to hold the sausage open with your fingers.)
Top with shredded cheddar Colby cheese. Place in 375℉ oven until cheese melts.
Top with quick pickled jalapeno and banana peppers, grated parmesan, bbq seasoning, and a drizzle of bbq sauce.
