My brunch menu was a mix of Caribbean and traditional American brunch foods. Many of the items were made the day before, which saved time the day of. Some items that are great for making ahead are: spinach quiche and deviled eggs.
I also got mini cupcakes from the grocery store. How cute are these mini desserts?! I think they are the perfect serving size for kids—and adults (still trying to get snatched for Summer). Most of these items can be prepared the day before and reheated or put out at room temperature when you are ready to serve.
You can find many more recipes in my brunch eBook, including roasted lamb.
