Gyro Meat Loaf with Tzatziki Sauce

I have been wanting meat loaf for a few weeks, and found this recipe.  D said he would make it.
It was supposed to be made with store-bought Tzatziki Sauce, but it was quicker to just make it then go hunt however many stores to find it.

It was lamb with spinach and cheese.  How could it be bad?  We had it with Greek Potatoes (2 baking potatoes, sauteed with Greek Seasoning, salt, and pepper, and some vinegar.

We will have again.

Gyro Meat Loaf with Tzatziki Sauce

A spin on a classic meat loaf, I love this because I can sneak spinach in on my meat-and-potatoes family. Serve it with Greek-style potatoes or a Greek salad. I also get to make a whole other meal the next night with the leftovers—gyros.
