Make Seasoning Blend, Prep Butter Toppings, Cut Veggies
Combine all blackened seasoning ingredients in bowl, mix well. Slice up the red onions, tomatoes, and shred the lettuce. Add the chopped parsley and minced garlic into a small bowl with butter (don't melt it yet).
Cook Bacon & Sear Salmon
Cook bacon until crisp using your desired method. Cut salmon into 3" even sized pieces. Drizzle with olive oil then season liberally on all sides with blackened seasoning.
Add a few tbsp olive oil to a skillet over medium heat and sear the salmon. Cook until salmon is crisp on all sides but not overcooked, about 1-2 minutes per side. It may take a few rounds as you don't want to crowd the pan. Tent it on a plate and set it aside.
Toast Buns & Assemble Sliders
Toast the undersides of the slider buns under the broiler for about 2 minutes, monitoring them to ensure they don't overcook. Remove the bottom buns and set aside, then flip the top buns, spread the melted garlic butter over the tops of the bun and broil for another minute or two, turn off oven.
Build the sliders by adding mayo to each side (top and bottom) of the sliders. Then add the warm salmon, top it with a dallop of honey mustard, then a piece of colby jack cheese. Warm it in the (turned off) oven for 2 minutes just so the cheese softens and partially melts. Then add crispy bacon, tomato, red onion, lettuce, and another drizzle of sauce. Place the top sides of the buns on top, slice and enjoy.
