If you like bell pepper, onions, and celery in your meat loaf, you may find that it may remain pink even though the beef is cooked to 160°F in the center. It's due to the natural nitrate content of these ingredients. So it is best to always check meat loaf with a thermometer to make sure it is thoroughly cooked.
Use ground turkey for the beef. Bake about 60 minutes or until a meat thermometer inserted in the center of the loaf reads 165°F.
You can use 1/3 cup dry bread crumbs or 1/2 cup quick- cooking oats for the 2 slices bread. Just add it to the beef mixture.
Almost any size pan will work; just be sure the pan has sides to catch the juices that will accumulate while the meat loaf bakes.
Cut a small slit near center of loaf; meat and juices should no longer be pink.
