Tips & Substitutions
For a more tender steak, marinate it in the lemon juice mixture for a few hours before cooking. You can substitute round steak with flank or sirloin if preferred. If you want extra flavor, consider adding garlic or Worcestershire sauce to the mixture. For a vegetarian option, try using portobello mushrooms instead of steak, which pairs beautifully with Vegan recipes.
