Since you have a gas grill (as we do), can you give me an idea of how long it takes to heat up those cast iron pans?
My cast iron pans take about 10 minutes to heat up with my 4 burners set on High. My gas grill’s bottom is rusted out, so that’s all I use it for is cooking on the cast iron outside.
Now I imagine a larger griddle may take a few extra minutes to heat up. But what’s 15-20 minutes when an oven, normal gas grill, chimney of charcoal takes the same amount of time? A griddle will give you that extra surface area as opposed to doing your tenderloins in batches in a pan.
Also, most griddles are reversible. You could use the side with the raised ridges if you’re looking to obtain some nice grill marks.
You could see it gives you a good sear using the cast iron on a gas grill.
