Preheat oven to 375 degrees F.
Crumble sausage into pan, add 1 tablespoon of the Mexican seasoning, tomato sauce, and beans. Cook on medium heat for 5 minutes, stirring occasionally. Add diced peppers and let simmer for another 8 minutes. Set aside.
On a floured surface, unroll dough to fit in 15-inch round pan. Arrange sausage filling around sides of dough. Top with cheese and black olives. Using a pie cutter mark 8 slits in the center of the pan. Gently lift each triangle over the filling and tuck tip under the sides. Repeat with remaining triangles. Bake for 20 to 25 minutes or until crust is a golden brown. Serve warm.
