Slice the yellow onion into half-inch thick rings and set aside.
In a small bowl, combine the Greek yogurt, lemon juice, hot sauce, and half of the smoked paprika to create the zesty dip.
Season the chicken breast with the remaining smoked paprika, garlic powder, sea salt, and black pepper.
Grill the chicken over medium-high heat for 6 minutes per side until succulent and fully cooked, then slice into strips.
In a medium bowl, whisk together the whole wheat flour, light beer, and egg white until a smooth, bubbly batter forms.
Dip each onion ring into the batter, place in the air fryer basket, and lightly spray with avocado oil.
Air fry at 375 degrees Fahrenheit for 10-12 minutes until the coating is golden and crispy.
Serve the hot onion rings immediately alongside the grilled chicken strips and the chilled zesty dip.
