Melt the butter in a small dish over the stove or in the microwave. Set aside to allow it to cool down.
Heat 1 teaspoon of olive oil in a skillet over medium heat. Place the tomatoes and Canadian bacon into the skillet, sprinkle the tomatoes with a pinch of salt and pepper.
Cook the tomatoes and Canadian bacon on both sides for 2 minutes each.
Poach the eggs using preferred method.
Toast the English muffins to liking. Add 2 toasted English muffin halves onto 4 plates. Set aside.
Hollandaise Sauce:
Place the egg yolks and lemon juice in a blender. Blend on high speed for 30 seconds until combined. Give the melted butter a quick whisk to combine any bits that separated.
Working quickly and with the blender running on medium speed, remove the lid insert and slowly pour the melted butter into a blender in a thin stream. Blend until a creamy sauce forms.
Season to taste with salt and pepper and add a little more fresh lemon juice, if desired.
To Assemble:
Top the English muffin halves with 1 slice of Canadian bacon, followed by a tomato slice.
Carefully top with poached egg and generously drizzle each with prepared hollandaise sauce. Sprinkle with fresh ground pepper, if desired.
