Preheat the oven to 350°.
In a large bowl, mix together the ground beef, pork, bread crumbs, egg, and 3/4 cup salsa. Add the lemon juice, brown sugar, parsley, cilantro, salt, chili powder, garlic powder, cumin, and cinnamon. Mix well and pack into a 9x5-inch loaf pan.
Bake the meatloaf for 45 minutes. Spoon the remaining 1/4 cup of salsa over the loaf and return to the oven. Bake for 25 to 30 minutes longer, or until cooked through. The meatloaf should register at least 160° in the center.
