Steam broccoli, covered, 5 minutes or until crisp-tender.
While the broccoli cooks, combine cream cheese, dressing, and Italian seasoning in a bowl.
Combine broccoli, cream cheese mixture, turkey, and bell peppers in a medium nonstick skillet; cook turkey mixture over medium-high heat until thoroughly heated, stirring frequently.
Slice focaccia in half horizontally; place halves, cut sides up, on a baking sheet. Broil 1 minute or until toasted. Spread turkey mixture evenly over bottom half of focaccia; top with remaining focaccia half. Cut into 4 wedges.
