Grilled Flank Steak With Chile Spice Rub -- works with skirt steak, too. Use sea salt in the rub, and skip the olive oil for Phase 2.
Homemade Balsamic Vinaigrette Salad Dressing uses just a few ingredients you've probably got in your kitchen. Great to mix up a jar and keep it on hand for Phase 3.
Another easy 5-star dinner: Pork Tenderloin with Seasoned Rub
Machaca aka Slow Cooker Beef Brisket -- sub tamari for the soy sauce. Super-flavorful for Phase 3 (without the Worcestershire) or Maintenance.
