Preheat the air fryer or oven to 400°F.
Toss the green beans and sliced bell peppers with olive oil, sea salt, and black pepper.
Roast the vegetables for 12-15 minutes until they are tender and slightly charred.
In a medium bowl, mix the ground turkey, egg whites, garlic powder, and smoked paprika until well combined.
Form the turkey mixture into one large, thick patty.
Heat a non-stick skillet over medium-high heat and sear the patty for 5-6 minutes per side until fully cooked.
Toast the slice of Dave's Killer Bread until golden brown and firm.
Spread the mashed avocado onto the toast and top with the cooked turkey burger and salsa.
Serve the roasted vegetables on the side for a complete meal.
