Ingredients
1   egg, slightly beaten
3/4  cup soft rye bread crumbs (1 slice)
3/4  cup shredded provolone or mozzarella cheese (3 ounces)
3  tablespoons beer, milk, or water
2  tablespoons purchased pesto
1/4  teaspoon ground nutmeg
1/4  teaspoon pepper
1  pound lean ground beef
   Sliced provolone or mozzarella cheese (optional)

Directions
1. In a large bowl, combine egg, bread crumbs; cheese; beer, milk, or water; pesto; nutmeg; and pepper. Add ground beef; mix well. Form into a loaf, and place in an 8x4x3-inch loaf pan. 

2. Bake in a 350 degree F oven for 45 to 50 minutes or until meat is done (160 degree F). 

3. Remove from oven. Transfer to a platter. If desired, diagonally halve slices of provolone or mozzarella cheese. Place three cheese triangles on top of meat loaf. Let stand for 5 minutes before slicing. Makes 4 servings. 

Test Kitchen Tip: For safety’s sake, ground meats (pork, veal, or beef) need to be cooked to 160 degree F; ground poultry (chicken or turkey) should be cooked to 165 degree F. An easy way to check the temperature of ground meat dishes is to use an instant-read thermometer. Insert the thermometer about 1/4 inch into the loaf for 10 seconds.
