Preheat a non-stick pan over high heat.
Slice the English muffin in half.
Spread cream cheese or butter on the inside of each half of the English muffin.
Place the English muffin halves, cream cheese or butter side down, on the hot pan.
Cook for 3 minutes or until the inside is browned and cream/butter is fried into the muffin.
Place the rest of the butter/cream cheese on the English muffin, then flip the English muffin halves (butter/cream now on the heat source)
Place a slice of cheese on each half. Cook for another 1-2 minutes or until the cheese starts to melt slightly.
Spoon guacamole on one of the halves, then place the other half on top, making a full sandwich.
Press the sandwich together gently, then flip and cook for a few more seconds or until it's browned to your preference.
Remove from the pan and let rest for at least 1 minute before slicing and serving. Enjoy this pan fried goodness.
