Rich Person's Prime Burger with Truffle Aioli, Arugula, Grilled Onion and Portobello Mushroom
1 lb. USDA Prime steak
2 T. mayonnaise, home-made or store-bought
1 T. honey-truffle mustard
1 t. truffle paste or truffle oil
2 slices truffle cheese
2 portobello mushrooms
2 slices sweet onion
1 T. truffle oil
1 handful arugula
6-8 sun-dried tomatoes, packed in olive oil
Salt & freshly ground black pepper
2 hamburger buns
The burger: Cut steak into ½-inch cubes, trimming any tough connective tissue, refrigerate until thoroughly chilled. Place steak cubes in food processor and pulse until coarsely ground (don't over-process; you don't want paté). Check for any big chunks or tough pieces and remove. Form into two patties and season to taste with salt and pepper.
The aioli: Mix mayo, mustard and truffle paste or truffle oil. Refrigerate.
To prepare: Preheat grill or sauté pan. Brush onion slices and mushrooms with truffle oil and grill-sauté until lightly caramelized. Set aside. Salt and pepper burgers and grill-sauté until done to your preference. Put cheese on top and let melt. Toast buns or croissants.
To assemble: Spread buns-croissants with truffle aioli. Place arugula on bottom half, top with burger. Top burger with onion slice, mushroom, sun-dried tomatoes and other half of bun. Scarf like a Rich Person.
