Add all ingredients to stand mixer and mix until incorporated. Add to greased bowl and allow to rise overnight in refrigerator (optional step but it adds a lot of flavor. It can be left for several days also). Allow rolls to come to room temperature and weigh out into 12 buns. Add to 13X9 casserole or half pan, weighing out 12 balls of dough to make 12 sandwiches. Allow to rise until double in warm area, this could be an hour and a half to 2 hours. Bake at 350 degrees Fahrenheit for about 25 minutes until internal temperature reads 190 degrees Fahrenheit. Brush tops with melted butter with garlic powder added.

Bake patty in 13X9 pan or half pan at 350 degrees Fahrenheit for 30-45 minutes, until internal temperature reads 165 degrees Fahrenheit.

Add all ingredients and warm in microwave until the beef base melts, stir.

Slice slider buns in half horizontally and add sausage patty (save top for later). Add sauce to top, and cheese on top of sauce. Bake in preheated 350 degree Fahrenheit oven until bottom bun is warmed through, patty is warm and cheese is melted. This could be 30-50 minutes depending on starting temperature of the buns and meat. When the bottom is nearly heated through, add the top bun (I used a separate pan) and heat that through. Remove bottom from oven, add hoagie spread, lettuce and onions, then top bun. Cut sliders and serve.
