Sorry, I don't have a recipe, because I haven't done Rotisserie anything in such a long time. (But this thread makes me want to dig out that old appliance and see if it still works because rotisseried stuff was delicious.)
You can basically use any recipe that you would use for roasted chicken. The sky's the limit and your taste palate is your guide.
If you want it to taste like the store bought rotisserie chicken
maybe ask them how they spice it. In fact, if I remember correctly, I do believe the packaged rotisserie chicken comes with an ingredient sticker on it.
Check your appliance "How to" guide for temperature settings and cooking times . . . a lot of specialty appliance manuals come with starter recipes. If you don't have your book any more you can always google the name brand.
Your rotisserie appliance might be different from mine, so I wouldn't even begin to try and tell you that for chicken you should be on the 3rd slot up, 2 or 3 inches away from the heating element for xHours . . .
Mine is open air with one heating element on the bottom (an indoor electric grill type of thing.) Yours (a toaster oven?) sounds like it's enclosed. KWIM? All appliances are different.
Remember that you can also use your rotisserie for other things like beef or pork roast and large shish-kabobs (just skewer anything you would on a normal sized shish-kabob but with larger chunks of whatever.)
Have fun with your new toy!
