Recipe scares me. People tend to overcook the hell out of shrimp. Mine just hit the grill 2-3 minutes on each side. leaving shrimp on there till the chicken, which is insulated by the shrimp on the inside, to get done, and waiting for bacon to get crispy is screaming for soggy bacon, overcooked shrimp, and undercooked chicken.
Would have to be extremely skillfully executed, and by the looks of your pron. you seem to have pulled it off. As long as the shrimp dont feel like erasers in your mouth
