In a large mixing bowl, combine ground turkey, yellow onion, jalapeño, honey, smoked paprika, thyme, cumin, and salt. Mix thoroughly until incorporated.

Divide the mixture into 3 to 4 equal portions and shape each into a burger patty, creating a slight well in the center.

Heat a nonstick skillet over medium heat, drizzle oil, and place the patties in the skillet. Cook for approximately 5 minutes on one side, then flip and cook for another 5 minutes.

In a blender, combine avocado, cilantro, sour cream or Greek yogurt, lime juice, and salt. Blend until smooth and creamy.

Slice the hamburger buns and toast them cut-side down in the same skillet until golden brown.

Spread avocado crema on the top and bottom buns, place cooked turkey patties, add corn salsa and cilantro if desired, then top with the bun.
