The Best Hamburger Sliders with Truffle Mustard

Mmmmm....hamburger sliders with cheddar, blue cheese and truffle mustard.    

 We have been on a truffle mustard kick around here.  It's so easy to make and killer delicious!  Just mix a jar of country dijon mustard, 2 tsp. yellow mustard and truffle oil to taste. I add lots of the oil!  Mix it thoroughly and eat it on anything you would use mustard on. Heaven!  The guys wanted sliders the other day so I made them these.  They said these were the best they have ever eaten.  They took 15 minutes to make.  Start by brushing slider buns with melted butter.

 Form small burgers about 1 inch thick.

 Crack sea salt and black pepper on them.

 Cook on a griddle pan over high heat.

 Broil the buns.

 Cover one side of the buns with crumbled blue cheese and the olther side with a good sharp cheddar. I used a Double Gloucester.

 Cook the burgers until they have a nice crisp exterior but are still on the rare side in the middle.  They continue to cook a bit when removed from the heat. You want these medium rare and not well done.

 Place a burger on each bun.

 Top with a heaping spoonful of the truffle mustard and munch away!
