Lightly spread the butter on one side of each slice of bread. On a skillet on medium-high heat, toast the bread butter-side-down until it is lightly golden, about two minutes. Flip the bread, turn off the heat and let the residual heat toast the other side.
Mix together the honey, Frank's red hot and red pepper flakes to make a hot honey. Pour this over the chopped walnuts and toss to combine.
Spread a thin layer of ricotta cheese on each slice of bread. Top liberally with the blueberries, then the hot honey walnuts. Add salt and pepper to taste if you prefer, but it doesn't need it!
Enjoy whenever!
