While the chicken is marinating, combine the chicken broth, peanut butter, honey, coconut aminos, ginger and garlic in a small saucepan and bring to a simmer over medium heat, then reduce to low, stirring frequently. Cook for several minutes or until the sauce is smooth and has thickened. Remove from heat and whisk in curry powder, chili paste, and lime juice. Sprinkle with salt and just seasonings to taste. If you want a thinner sauce, just add a little water. Set sauce aside or store in the refrigerator until the chicken is ready.
