Grow and grill?? Gardening questions

I don't know how big you are going. But I have always wanted to get some of these and plant peppers in them.

This past year, we had quite a bit of success with potatoes, kale, cabbage, and garlic. We did get some tomatoes, but they weren't terribly big. Garlic was already planted for this spring (in late October)... looking forward to growing even more potatoes!
