Hmmm..that's weird. I just clicked on the link and it opened for me. Here it is again: http://www.genaw.com/lowcarb/spinach_lasagna.html

But here also is the recipe:
SPINACH LASAGNA
1 pound ground beef
2 tablespoons onion, chopped
1/8 teaspoon garlic powder
1/2 cup spaghetti sauce
8 ounces cream cheese
1 egg
1/8 teaspoon pepper
10 ounces frozen chopped spinach, thawed & drained
4 ounces mozzarella cheese, shredded
2 tablespoons parmesan cheese (I used the kind in a can)

Brown the hamburger with the onion; drain off the fat. Mix in the garlic powder and spaghetti sauce; season to taste and heat until bubbly. Meanwhile, soften the cream cheese in a medium-size microwaveable bowl for about 40-60 seconds. Stir until creamy; beat in the egg and pepper with a spoon until well mixed. Blend in the spinach. Spread half of the meat mixture evenly in the bottom of a greased, 8 x 8" glass baking pan. Spread the spinach mixture over the meat; top with the mozzarella, then the rest of the meat. It may not completely cover the top, but that's ok. Sprinkle with the parmesan cheese. Bake at 350º about 30 minutes until hot and bubbly. Or, cover with plastic wrap and vent one corner then microwave on HIGH for 3 minutes; then reduce to MEDIUM and cook for another 7-10 minutes until hot and bubbly. Let stand 3 minutes before serving.
