Begin by assembling your sandwich. Smear ricotta onto one slice of bread and top with bacon. Add the basil, the spinach, and the Taleggio. Top with the other piece of bread and set aside. In a medium sized skillet, add olive oil and red pepper flakes and heat over medium for a few minutes until the flavors start to meld and become fragrant. Add the sandwich to one side of the pan and cook for a few minutes until a beautiful golden brown crust starts to develop. Flip the sandwich to the other side of the pan; making sure to smudge it around, sopping up of the remaining red pepper flake infused olive oil. Once that side becomes golden brown and the Taleggio begins has melted remove the sandwich from the frying pan and set aside for a minute or two before devouring.
