1. Trim ends and bottom from Panettone. Cut into 1 inch slices.
2. Combine eggs, milk, eggnog, spices, and salt, and lightly beat in a large shallow bowl.
3. Heat canola oil in a nonstick pan, using a paper towel to spread and remove excess.
4. Dip each slice in egg batter on both sides. If you prefer a more custardy texture, allow to sit for 30 seconds or so on each side.
5. Cook one or two slices at a time to golden brown, about 3 minutes on each side.
6. Transfer to a plate and serve with your preferred accompaniments.
