I worked in a bake shop in Houston that was only open for breakfast and lunch. All of the usual bakery items were made and sold there, but what really kept them busy was their simple menu. It consisted of really good chicken salad, tuna salad, and a few hot dishes that were easy to prepare in large quantities. Of course, the homemade bread was key. Pretty much like the Donut Hole but not as expensive and way more limited menu. They were packed for lunch because it was a quick, easy menu that never changed and was under $8.00 so people knew exactly what to expect when they got to the counter. Best of luck!
