In a large bowl mix patty ingredients. Tear or cut parchment paper into 6inch squares (you will need at least 19). Place a tortilla on the center of a parchment square. Sprinkle with parmesan cheese. Using a 2oz food scoop, place a portion of patty mix to center of each tortilla. Cover with another layer of parchment paper. Use a burger press (or small frying pan) to flatten out each scoop of patty mixture on to each tortilla. Repeat with remaining tortillas. **Meat should be pressed all the way to the edge , and even over hanging. It will shrink up while cooking.
In a large saute pan over medium-high heat, add bacon. Cook until crispy and remove to paper towel covered plate. Allow to cool some before chopping into bites. Reserve 2 tablespoons of bacon grease in the pan.
In a small bowl, combine romaine, Caesar dressing and remaining parmesan cheese.
Begin frying patty/tortilla, patty side down, in same pan bacon was fried in. Cook for approximately 3 minutes on patty side, then flip and cook for 2 minutes on tortilla side. Repeat with remaining smashtacos.
Add a portion of salad to the top of each taco and sprinkle with bacon bits. Repeat with remaining smashtacos.
