In a shallow dish, combine 1/2 cup flour, 1 tablespoon ginger, 2 teaspoons paprika, 1 teaspoon salt, 1 teaspoon nutmeg, 1/2 teaspoon pepper, and 1/2 teaspoon thyme; mix well and set aside.
In a separate shallow dish, beat 1 egg with 2 tablespoons water until combined.
Pat the 2 chicken breasts dry with paper towels. One at a time, dip each breast into the egg wash, then dredge in the flour–spice mixture, pressing the flour mixture onto both sides to coat. Place coated breasts on a plate. Discard any flour that contacted raw chicken—do not return it to the flour container or bag.
Heat a nonstick skillet over medium heat until hot. (Do not add ingredients not listed.)
Place the coated chicken breasts in the skillet and cook until golden brown and cooked through, about 5 minutes per side depending on thickness. Cook until juices run clear and the chicken is no longer pink in the center.
While the chicken is cooking, combine 1/2 cup honey, 2 tablespoons soy sauce, and 1 tablespoon minced garlic in a small saucepan. Heat over medium-low, stirring frequently, until the sauce is warmed through and slightly thickened.
Reduce the sauce heat to low to keep warm. When the chicken is done, transfer to plates and spoon the warm honey-soy garlic sauce over the chicken.
Serve immediately.
