Clean the potatoes and poke holes with a fork.  Microwave until the potatoes are soft through the middle.

While the potatoes are cooking, heat a skillet over medium high heat.  Add the hamburger to the skillet.  Once the hamburger is cooked about halfway through, drain a can of black beans.  Add half the can of black beans (or more, to your liking) to the skillet.  Once the meat has cooked through, add the taco seasoning, per the package instructions.  Set the meat mixture aside.

When the potatoes are finished cooking, cut each potato down the middle and squeeze the outside to open.  Stuff the potato with the meat mixture, then top with salsa, shredded cheddar cheese, diced avocado, chopped tomatoes, crushed up Doritos, and sour cream.
