Shelly's Spinach Beef Skillet Dinner

I adopted this recipe after the departure of my dear friend, Shelly. She had suggested it to me during one of my quests for dinner ideas, and I had prepared it quite some time ago with delicious results. At that time, I used fresh spinach which I added to the saute pan briefly with the cooked ground beef and onion and cooked just to wilt down. It was an easy comfort meal for us. Shelly's witty and insightful comments on the original recipes were as follows: So much better than hamburger helper! I got this from the "Southern Living" website before it required that you be a subscriber to the magazine to look at their online recipes. The original recipe calls for a 13 1/2 oz. can of whole leaf spinach, but I hate canned spinach so I use frozen. In fact, sometimes I use two boxes of frozen spinach instead of just one. The original recipe also called for just one cup of cooked macaroni but that just didn't seem like enough. You can also add another can of tomatoes if you like. Experiment! So easy and delicious!
