Looks good.
I just did something like this yesterday. I made dogs and tots before my kids baseball practice. So I didn't have time to get the grill going. So I had this crazy idea to bake the hotdogs in the toaster oven while the tater tots where cooking. This allowed me to do other things and not baby sit them. So I had it set at 250 for about 20 minutes. My kid hates any bit of char marks (grill or pan) and this solves my problem perfectly. It also allowed it to char up faster in the pan when making mine and the wife's. Made up 4 chili dogs, put them in an 8x8 pan, and baked that for an extra 2 minutes. Warmed and toasted the buns perfectly.
