In a bowl, combine the salt, pepper, harissa and soy sauce. Mix well. Work into the ground chicken and combine well.
In a separate bowl, take the diced jalapeno (seeds removed during dicing) and the pineapple and mix well. Set aside.
Heat your outdoor grill on medium heat. Cook the chicken burgers about 7 minutes per side. Bring inside and let rest for a couple of minutes.
Assemble the sandwich by placing a piece of lettuce on the bottom bun. Next, top it with the burger. If you are using a BBQ sauce, apply now. Top with the pineapple jalapeno salsa and avocados if you like.
Serve and enjoy!
I put the lettuce on the bottom bun so the burger does not make the bun soggy.
