Refer to my pork tenderloin recipe linked and follow the recipe. If not, make sure you have some pre-cooked protein.
Pre-heat Blackstone to 300℉ (or oven/stove)
Slice the loaf of bread lengthwise into two halves (if cooking on stove may also want to slice into sandwich size chunks)
Lightly butter your preferred surface (we used Blackstone). Start heating pork directly on the Blackstone or skillet.
Place bread facedown until heated (a minute or two) then flip over and start building your cuban.
Layer cheese and pork (can cover until it get melty) and let sit another minute
Add pickles and spread mustard generously.
Combined the sandwich halves and press down with a grill press or spatula.
Slice your sandwich into your preferred serving sizes and serve with a side of mustard.
