In a medium skillet on medium heat fry the bacon 3-4 minutes per side. Ideally you want to weigh it down, really press it into the pan to develop that maillard goodness
Remove the bacon from the pan and form into a tight pile roughly the size of the bread you'll be using, top it with the havarti, cover with a pot lid and set aside. The bacon's residual heat will melt the cheese
If you don't have an egg ring, skip this step and just fry your egg how you like.Place your egg ring in the center of the skillet and cover with a lid for about a minute. We want to preheat it so the outside of the egg sets immediately and doesn't run underneath.
While your ring preheats whisk together the egg, cream, salt and pepper in a small bowl
Poor the egg into the ring, after 20 seconds or so reduce the heat to medium-low, cover and allow to cook to desired done-ness. For me that was about 3-5 minutes.
Spread both pieces of toast lightly with the mayo, place the meat and cheese on the bottom, followed by the peppers, then the egg and optionally a light drizzle of HP sauce.
