Preheat oven to 375°F (190°C).
In a large skillet, cook ground beef, onion, and garlic over medium heat until meat is no longer pink. Drain.
Stir in flour, salt, and pepper until blended. Gradually add broth. Bring to a boil; cook and stir for 2 minutes or until thickened. Stir in peas and carrots; remove from heat.
For crust, combine flour and salt in a large bowl; cut in butter until crumbly. Gradually add ice water, tossing with a fork until dough forms a ball.
Divide dough in half so that one ball is slightly larger than the other. Roll out larger ball to fit a 9-in. pie plate; transfer to pie plate. Trim even with edge.
Add filling. Roll out remaining dough to fit top of pie; place over filling. Trim, seal, and flute edges. Cut slits in top.
Bake for 35-40 minutes or until crust is lightly browned. Let stand for 15 minutes before cutting.
