Season chicken, if desired, with salt and pepper. Heat oil in large nonstick skillet over medium-high heat and cook chicken, turning once, until browned, about 3 minutes; remove and set aside.
Add ham to same skillet and cook over medium-high heat, stirring occasionally, until crisp. Add sweet potatoes and onions and cook, stirring occasionally, until lightly browned, about 4 minutes. Stir in garlic and cook, stirring, until fragrant, about 30 seconds.
Add spinach, water, coconut milk, Knorr® Chicken flavor Bouillon and chicken and bring to a boil over medium-high heat. Reduce heat and simmer, covered, until chicken is thoroughly cooked, about 15 minutes. Remove chicken and shred; return to skillet. Serve with hot cooked rice, and, if desired, lime wedges.
