Place on a foil lined baking sheet and into the freezer for one hour.
Remove from the freezer and place 4 sliders each in 3 plastic zipper bags.
Since I don’t have a fancy vacuum sealer, I simply use the “water displacement method” of placing the airtight sealed bag with the sliders in it, almost all of the way under the water, leaving just about an inch of the top of the bag open, the water will press out all of the air around the food in the bag, you can then seal the bag closed.
Place the bags of sliders in a sous vide set to 130°F (for medium rare to medium – for medium to medium well, set the sous vide at 138°F) for 45 minutes – 3 hours.
Remove the sliders from the sous vide and the plastic bags and let rest on a paper towel lined cutting board for 10-15 minutes.
Before serving, heat the olive oil in a cast iron skillet over high heat.
Add the sliders and sear for 20-30 seconds per side.
Alternatively, you can grill the sliders on high heat for 20-30 seconds per side.
Top with a slice of cheddar cheese and serve on Hawaiian rolls.
