The Griddler Rocks!
So my future mother-in-law gave me a Cuisinart Griddler for Christmas and we used it for the first time last night. I know it was only around $129 at Amazon, and I was so impressed with the quality. It is basically built like a sandwich press or George Foreman grill, but it has a fairly wide cooking surface and interchangeable flat or grill plates that are nonstick. The best thing is that it opens flat so you can use it as an open-faced grill or griddle. Also, there are different heat settings.
I made grilled tuna and it turned out beautifully.
Then, coincidentally, I was watching an epiosde of Kitchen Accomplished while eating the aforementioned grilled tuna, and Cat used one in the kitchen they were working on!
There are a number of brands of this type of grill/griddle. Check their temperatures before buying. I have one made by LaFlamme, and when used with flat plates as a griddle, it doesn't get hot enough to do pancakes, french toast, etc. very well. It does meat and chicken just fine, but takes a lot longer than the Foreman grill.
