1. Heat a large skillet over medium-high heat. Add oil to pan; swirl. Add onion; sauté 4 minutes. Add garlic; sauté for 30 seconds, stirring constantly. Stir in beef. Sprinkle with salt and peppers, and sauté 3 minutes or until browned, stirring to crumble. Stir in sauce and olives.
2. Preheat broiler.
3. Steam cauliflower 4 minutes or until crisp-tender. Place cauliflower in an 11 x 7-inch broiler-safe baking dish coated with cooking spray; top with sauce mixture.
4. Place bread in a mini chopper; pulse until coarse crumbs form. Combine crumbs and cheese; sprinkle over cauliflower mixture. Broil 4 minutes or until browned.
Wine Match: When in Rome, drink like the Romans: A light, easy-drinking Italian red with good acidity pairs well with the tomato-based sauce and beef in this Italian-style recipe. Try Castello Banfi's Col di Sasso 2008 ($8), a soft and fruity blend of cabernet sauvignon and sangiovese, which has a hint of earthiness that enhances the olives and cauliflower. --Gretchen Roberts
