In a small bowl, combine the bread and milk; set aside. In a medium skillet, heat 2 teaspoons of the canola oil over medium. Add the onion and a large pinch of salt, and cook, stirring often, until the onion begins to soften, 1-2 minutes. Add the garlic and cook, stirring often, until the onion is translucent and the garlic is softened, 2-3 minutes. Transfer to a large bowl and let cool.
To the onion mixture, add the meat, egg, oregano, coriander, cumin, cinnamon, nutmeg, 1 teaspoon pepper and 1/2 teaspoon salt. Squeeze the excess milk from the bread (discard the milk) and add to the bowl. Mix together gently with your hands until evenly distributed. Form into about 20 balls slightly smaller than a golf ball.
