In a mixing bowl, combine honey, black pepper, olive oil, and salt. Add chicken breasts and coat well. Marinate for at least 30 minutes.

In a pot, bring salted water to a boil. Add penne pasta and cook according to package instructions until al dente. Drain and set aside.

Heat a grill pan over medium heat. Grill marinated chicken for about 6-7 minutes on each side or until fully cooked. Remove from heat and slice.

In the same pot, add garlic and sauté for 1 minute. Pour in heavy cream and bring to a simmer. Stir in parmesan cheese until melted and add spinach. Mix in cooked pasta.

Spread butter on one side of each ciabatta slice. Layer mozzarella cheese and sliced grilled chicken between two slices. Grill in a panini press until golden brown and cheese is melted.

Plate the creamy pasta and top with sliced honey pepper chicken. Serve with the grilled panini on the side.
