"Growing up in New Mexico, we had access to the Hatch green chile (the best!). I add green chile to a lot of my recipes and it rather sets this meatloaf off. It's very good cold, made into sandwiches the second day."
Preheat oven to 350 degrees F (175 degrees C). Grease a loaf pan.
Mix hamburger, tomatoes, green chiles, onion, milk, eggs, crackers, salt, and pepper together in a bowl. Transfer to the prepared loaf pan.
Bake in the preheated oven until until no longer pink in the center, about 1 hour and 10 minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
Let cool in the pan for 10 minutes before transferring to a serving dish.
