Heat oven to 425 degrees.
Lightly grease jelly roll pan, 15.5 x 10.5 x 1 inch, or cookie sheet (we use two 9 inch cake pans with excellent results).
Mix baking mix and water until soft dough forms; beat vigorously 20 strokes. Gently smooth dough into ball on floured cloth-covered board. Knead 20 times. Pat dough in bottom and up sides of pan with floured hands. Or roll into rectangle, 13x10 inches, and place on cookie sheet; pinch edges of rectangle, forming 3/4 inch rim.
Cook and stir ground beef, onion, salt and garlic until beef is brown.
Mix tomato sauce and Italian seasoning; spread over dough. Spoon beef mixture over sauce. Top with remaining ingredients.
Bake until crust is golden brown, about 20 minutes.
