1 lb lean ground beef
1 lb ground turkey
1 1/2 C old fashioned rolled oats, NOT steel cut
4 cloves of garlic, chopped
1 medium onion, chopped
1 large celery stalk, chopped
1 mediun carrot, chopped
1/2 C parsley, chopped
2 large eggs
1/4 C ketchup
1 T Dijon mustard
1/4 C chili sauce
1 T soy sauce
2 t salt (3 t if using course salt)
1/2 t black pepper

Topping:
1/2 C ketchup
2 T brown sugar

Preheat oven to 375 degrees.
Mix all ingredients (except those for topping) well, with a large folk or with your hands.
Transfer to a 9 X 5 inch loaf pan.
Mix the topping ingredients and spread on top of meat. 
Set pan on a bigger rimmed baking pan and bake about  70 – 75 min. When done, a knife inserted in the middle should produce clear rather than cloudy juice.
You can also bake in a 6 – 8 C (1.5 – 2 Qt) baking dish and this will cut down the time to about 1 hr.
