Cook ground beef according to directions on taco seasoning mix. Set aside.
Prepare the pizza crust according to package directions. For the Pillsbury Pizza Crust I used, I greased a pizza pan and spread the dough to fit. Then I pre-baked for 8 minutes in a 400°F oven.
Spread taco sauce over pizza crust, leaving a gap around the edge.
Evenly distribute ground beef, jalapeno slices, tomatoes, cilantro over the sauce. Then top with cheese.
Bake an additional 7 to 10 minutes or until crust is golden and cheese is melted. Serve with a side of sour cream for dipping, if desired.
