Most breakfast sandwiches are greasy, dense and full of bacon or sausage. These Veggie Breakfast Sandwiches are light and full of flavor. I love making these just for myself, or when I have friends over for breakfast/brunch. My trick is to use fresh brioche burger buns. They add such a nice sweet flavor to the savory spinach and eggs. These are simple, as breakfast sandwiches should be. No one wants to get up in the morning and work hard to get breakfast on the table.
