Preheat oven to 400°. Cut bacon strips crosswise in half. In a large skillet, cook bacon over medium heat until partially cooked but not crisp. Remove to paper towels to drain; keep warm.
Wrap a bacon piece around each Spam cube; secure with a toothpick. Place in a 15x10x1-in. ungreased baking pan. Bake for 10 minutes. In a bowl, combine mustard, syrup and garlic; drizzle over bacon-wrapped Spam. Bake until bacon is crisp, 5-10 minutes longer.

Not a fan of Spam? Use cubed cooked ham instead.
To make ahead, wrap the Spam with bacon and secure with a toothpick. Store bites, covered, in the refrigerator for up to 2 days.
