Cook bacon in a skillet over medium/medium-high heat for 5 minutes or so until brown and crumbly.
Remove from the skillet with a slotted soon and set aside. Then, add the onion and peppers into the skillet and cook in the bacon grease for about 5 minutes, or until softened.
Add the hash browns to the skillet and mix in with the vegetables. Cook 10 minutes on each side or until browned and crispy.
Place the crumbled bacon, tomatoes and avocado on top and serve.
