Making Meatloaf for the first time

I don’t think I’ve ever followed a meat loaf recipe.

2 parts hamburger
1 part Italian sausage
Between 5-10 eggs
An onion
Some Garlic
Some peppers
A little beef bouillon?
Salt/Pepper
Progresso Italian Bread Crumbs

I top it at the end with a glaze made from ketchup, brown sugar and squirt of mustard.
