You could also have homemade smoothies ready for your guests. Have a bunch of cut up or frozen berries, yogurt, coconut water, and juice. You could make the smoothies to order if you are so inclined. Another great addition would be whole grain waffles or pancakes or blueberry muffins. You could also have some savory muffins like a cheddar cheese muffin. Eggs are a great addition to a brunch. You could make a frittata with asparagus and ham. You could have bagels out with a variety of cream cheeses. So many yummy options for brunch.
