In small bowl, stir together the salad dressing, hot sauce and jalapenos.
Cover and refrigerate until ready to serve.
For the smash burgers
Fire up your grill for high heat. Place a griddle or a large cast iron pan over the highest heat.
Season the ground beef and form into four 4 ounce balls (not patties!).
Place the balls of beef on the griddle and let cook for one minute. Just let them cook, don't mess with them.
Take your press and flatten out the patties. I like to use the point of the press and work my way around the ball first, doing a little section at a time and then finally I press down on the entire patty to flatten it out. You can also just flatten out the ball all at once. At this point I also like to season the patties some more.
Let the patties cook until you start to notice a little char along the edges. Flip, season again if desired, and continue cooking another minute or so until the other side is charred. The burgers are thin so they will cook very quickly so watch out.
Add the cheese slices. If desired, cover in a dome to help the cheese melt.
Toast the buns. Remove, add the patties and serve topped with two pieces of the bacon and 2 tablespoons each of the guacamole. Add the onion and tomato if using.
Devour immediately.
Notes
Scoop up any guacamole that drips off your burger onto your plate with tortilla chips!
