Quick Tips for the Chef:

• For extra flavor, add a dash of Worcestershire sauce or soy sauce to the beef mixture before baking.
• Want more texture? Roast the cauliflower an extra 5 minutes for even crispier bites.
• For a spicier version, add a pinch of cayenne pepper or red pepper flakes.
• Make it ahead! Prepare the casserole up to two days in advance and bake when ready.
• Want a dairy-free version? Use dairy-free cheese and swap Greek yogurt for a plant-based alternative.
