This is FANTASTIC...my family and friends have all given it 5 stars and requested it again and again. I've never met a meatloaf I enjoyed making before this one. It really is enough to serve 12. For the average family, you can form it in 2 loaves in the 9x12 and have enough for two meals. Also, I just use regular mustard and I usually double the sauce recipe b/c everyone likes extra for rice or potatoes.. For badkitty...make sure the measure the vegetables...too many make it too moist and it will fall apart. Also, make sure to bake it until it reaches temp...then allow 10 minutes to "set up" after removing from the oven. This helps keep it from falling apart.
