Preheat the oven to 400 degrees and line a cookie sheet with aluminum foil or spray it with cooking spray.
In a medium pan, brown the beef until done. Once the beef is browned, drain the meat, add the taco seasoning to the pan and mix until combined. Set aside to cool.
Unroll the pizza crust onto the cookie sheet pressing into a rectangle.
Mix cream cheese and salsa in a small bowl. Spread cream cheese mixture lengthwise down center third of the rectangle. Distribute the seasoned meat and black beans evenly down the center. Top with the shredded cheddar cheese.
On each long side, cut 1 inch wide strips about 2-1/2-inches into center. Starting at one end, fold alternating strips at an angle across filling. Pinch ends to seal and tuck under. Brush the outside of the braid with olive oil and sprinkle with garlic salt.
Bake at 400 degrees for 15-18 minutes or until golden brown. Remove from oven and place on cooling rack or cutting board with two spatulas.
