• 2 tablespoons Butter (Quantity estimated (not specified in original recipe))
• 1/2 medium Onion (Quantity estimated (not specified in original recipe))
• 1/2 cup Chicken or Vegetable Stock (Quantity estimated (not specified in original recipe))
• 1/2 pound Lobster meat

• 1/4 teaspoon Black pepper (Quantity estimated (not specified in original recipe))
• 1 teaspoon Lemon juice (Quantity estimated (not specified in original recipe))

Instructions

1. 1Melt butter in a skillet over medium heat. Add sliced mushrooms and cook for 5 minutes, stirring occasionally. If desired, add sliced onion and cook until softened, about 3 minutes.
2. 2Pour in the stock and bring to a simmer. Cook until the mushrooms are very tender, about 10 minutes.
3. 3Chop the mushrooms and press them through a sieve. If the mixture is very moist, reduce it in the skillet over medium heat until it reaches the consistency of a thick purée, about 5 minutes.
4. 4Add the lobster meat to the mushroom purée. Season with salt, pepper, and lemon juice. If desired, add tomato ketchup. Stir to combine.
5. 5Let the mixture cool. Use as a filling for sandwiches.
