Lion’s mane steak sandwich (Argentinian asado style)

Name: Lion's mane steak sandwich (Argentinian asado style)
Ingredients: 3 lion's mane mushrooms (or oyster mushrooms); 4 tbsp soya sauce; 1 tsp liquid smoke (optional); 1 tsp smoked paprika; 1 tsp paprika; 2 garlic cloves (minced); 1 sprig rosemary; 2 tbsp plant-based margarine or oil; Salt (to taste); ½ cup fresh parsley (chopped); 3–4 garlic cloves (minced); 1 tbsp dried oregano; ½ cup sunflower oil; ¼ cup red wine vinegar; 1 tsp smoked paprika, chili flakes (optional)

A sandwich on a floral plate filled with mushrooms, spinach, diced tomatoes, and onions, with a blurred teacup and potted plants in the background.

This recipe transforms mushrooms into a juicy steak, inspired by the Argentine 'bondiola' or grilled steak sandwich. It reminds me of my childhood and family Sundays. Pairing it with chimichurri brings that smoky, savory nostalgia to life.
