You will also need: parchment paper to separate the patties and cooking spray to make it easier to form them
Add the ground turkey, grated onion, salt, Worcestershire sauce, paprika and black pepper to a large bowl. Combine the ingredients well by stirring the turkey mixture with a fork, or use your hands. Mix it just enough to combine well, try not to overwork the meat to avoid tough, dry patties.
Separate the turkey mixture into four equal sections. Work with one section at a time, shape the ground turkey into a ball and then shape into a burger, make the center slightly thinner that the outer part. Repeat with the remaining meat. You should end up with four ⅓ pound burgers.
Prep the toppings before grilling the burgers.
Make the chipotle mayonnaise: Combine the mayonnaise and chipotle hot sauce in a small bowl. Stir well with a fork to mix. Use more or less chipotle hot sauce, depending on taste.
Separate and wash the lettuce leaves, pat dry.
Slice the tomato
Prep the avocado last so it doesn’t brown, remove the seed, peel and cut into slices.
Grill the turkey burgers on a pre-heated grill over medium heat, flipping them occasionally, until the internal temperature is at least 165°F. The exact grilling time will depend on the thickness of your burgers and the temperature of your grill but use 10-12 minutes as a guide.
Right before removing the burgers from the grill, add the cheese and let it melt a little bit. The cheese will continue to melt with the burger’s residual heat.
Add the burger patty to the bottom bun and add the chipotle mayonnaise. Then top the burger with sliced avocado, lettuce and tomato. Enjoy!
