Korean chili pepper brings the Vietnamese Banh Mi to the next level. Spicy, rich, pickled and full of textures - this sandwich has it all.
Cut beef Cross Rib Roast into 2-to-3 inch pieces, season with pepper. Coat large nonstick skillet with nonstick spray; heat over medium until hot. Add half of beef; brown evenly, 3 to 4 minutes per side.
Transfer beef to slow cooker. Repeat with remaining beef.
