In a large saucepan over medium heat, simmer butter, olive oil, chili sauce, Worcestershire sauce, lemon juice, lemon, garlic, parsley, Anaheim chile, red pepper flakes, oregano and Tabasco until well blended. Remove from heat and let cool.
Place sauce in a zip-lock bag; add the prepared shrimp. Refrigerate at least 8 hours or overnight.
Preheat oven to 350 degrees F.

Place shrimp mixture in shallow bowls and serve with a crusty French bread for dipping in sauce (this dish is eaten with your fingers).
