The "OOH Chile" Blended Burger w/Truffled Peach and Jalapeno Aioli

This burger is BANANAS.I am proud of my creation, even though I didn't win the Bon Appetit Blended Burger Contest.  Now, I can share it with my readers!

RECIPE:

For Burger Blend:
24 oz. Western style Beef ribs, chilled and cut into 1/4 to 1/2 inch chunks
8 oz. Polska Kielbasa, skin removed and cut into 1/4 inch chunks
8 oz. BABY BELLA mushrooms, cleaned and cut into 1/4 inch chunks
1 tsp. nutritional yeast

For Assembly:
Fresh Butter Lettuce and Red Curly Lettuce
8 slices Pepper Jack 
8 slices Sharp Cheddar Cheese 
8 slices fresh tomato 
8 Brioche Buns
SPST (Salt and Pepper to Suit Taste)
I used Himalayan Pink Salt, fine grain

For Aioli: (can be made ahead)
1/2 c. Mayonnaise of choice 
1 small peach, de-seeded and grated
1/2 Jalapeño,cut lengthwise, seeds removed, 
grated, (more depending on preference) 
1 small clove garlic, pressed or finely minced
2 tsp. roughly chopped Parsley and Chives 
Zest of 1/2 Lemon  
1 tsp. lemon juice
Drizzle of Truffle oil or to taste
SPST (Salt and Pepper to Suit Taste)

Combine all ingredients in a small bowl and let flavors marry for several minutes or make ahead for more developed flavors. 

For Burgers:
In a medium bowl, toss meat and mushrooms together with the nutritional yeast.

Using a grinder attachment ( I used my meat grinder attachment for my Kitchen-aid, fitted with the small grind plate, but any grinder will do. 
Process the meat into a well mixed burger blend. Process only 1 time.
Form 8 patties.

Instructions:
Cook burgers over medium high heat using  a grill pan or on the grill for about 4 minutes per side.
Flip the burgers once, and continue until internal temperature reaches 160° or desired doneness.
Transfer to platter and let rest for several minutes while you assemble the rest of the burger. You may add the cheese slices now, a slice of each type per burger.

To assemble the burgers, start with lightly toasted bun, if desired.
Spread Aioli on top and bottom bun.
Add burger, tomato and lettuces.
