Heat oil. Cook onions, celery, carrots, garlic, and thyme until very soft. Let cool.

Meanwhile, mix the next 4 ingredients well. Incorporate the cooked vegetables. Pack tightly in a 10-inch loaf pan.

Combine the 3 remaining ingredients and spread half of it on top of meatloaf (save remaining sauce to serve with the meatloaf).

Cook in a water bath for 1 hour or until cooked the whole way through in 400 degree oven.

(This makes a pretty large meatloaf -- I usually divide the mixture in half and cook one loaf and freeze the other one. I think it just depends on the size of your family).
