My daycare meals are based around my supper meal plan. I cook in bulk and we do 'leftovers' for lunch. So, yes, we do have the same items in a week. Every week I roast a chicken, and we have leftovers. Every week I make spaghetti sauce, and we have leftovers. The rest varies...usually we have tacos every other week, casseroles are popular too (and easy for me).
Snack is always a fruit, a carb, a protein. For example, grapes, cheese chunks and pretzels. It's easiest for me to prepare that way and easy for the children to eat.
Also, whether or not something is a 'repeat' depends on what is on sale. When I can get grapes for $0.88/lb then we have grapes a lot that week...but when bananas are on for $0.44/lb then we eat those more.
