Coffee shop food

So I am struggling with wether to have donuts and kolaches, or just home baked goodies. Right now, I am thinking standard fare: cookies, cupcakes, rice crispy treats, cakes and pies. I would like to have some protein avaiable, but am not sure what, since I am limited by funds and the restrictions of the Texas bakers bill. I would love to offer quiche, but I don't think that will be a viable option. Thoughts? I think I will be making jelly rolls fairly often (mmmmm pumpkin cream cheese jelly roll), but what do y'all think of the donut situation?
