Preheat oven to 400.
Line bacon strips side-by-side on large (rimmed) cookie sheet. Cook bacon in oven for 15-20 minutes (until crispy). Remove from oven and set aside to cool a bit. Turn oven heat down to 350. Transfer the bacon strips to a plate lined with some paper towels to absorb some of the grease.
Now we're going to start assembling the sliders. The package of slider buns will likely be connected in 2 sets of 6 buns. Slice each set of buns in half (like a hamburger bun), and set the bottom half of the 12 buns in a 9x13 casserole dish.
Layer turkey slices evenly across the buns, then layer half of the cheese (8oz) on top of the turkey.
Peel, pit, and thinly slice two avocados, and layer the avocados evenly across the cheese.
Place the jalapeno slices evenly across the cheese between the avocado slices.
Layer bacon slices across avocados and jalapenos, and then add a final layer of cheese on top of the bacon.
Place the top halves of the slider buns on top of the cheese.
Melt butter in a microwave-safe dish (or on the stove top if you'd prefer), and then stir in the Ranch dressing and Worcestershire sauce. Drizzle sauce over tops of sliders.
Place casserole dish in the oven at 350 for 10-15 minutes, or until the tops of the buns are turning golden brown.
Remove from oven and serve as a delicious appetizer or as a meal with a side salad or roasted veggies. Enjoy with family and friends around your table!
