You will need:

• Mushrooms sliced  (2/3c per person)
• 1-2 Shallots sliced  (optional)
• Green Peppercorns (1/2 teaspoon per person)
• Just Aioli  (1 Heaped Tablespoon per person) or as needed to reach the desired consistency

Method:

1. Chop peppercorns roughly to release their flavour.
2. Cook the mushrooms, Shallots and peppercorns in a frying pan with a little butter until golden and caramelised.
3. Place in a bowl to cool (or they will cook the aioli.)
4. Place a large heaped tablespoon of garlic aioli per person into the bowl (I love "Just aioli" from the supermarket). 
5. Mix together and scoop onto steak.

I love serving an eye fillet or scotch fillet on a bed of rocket, or a green salad, or with some zucchini noodles tossed in garlic and herb salt with butter and a dollop or two of this sauce drizzled on top.
