Tunanesca Sauce

• 1/4 cup olive oil
• 2 tablespoons unsalted butter
• 1/2 small onion, small dice
• 1/2 fennel bulb, cored, small dice
• 1/2 teaspoon red pepper flakes (seeded chopped jalapeno or fresno chile would work, too)
• 3 anchovy fillets, minced
• 2 garlic cloves, minced
• 6 oz canned tuna in oil, drained and chopped
• 1/2 cup dry white wine
• 2 tablespoons parsley, finely chopped
• 1 cup diced tomatoes, drained
• 1/3 cup pitted black olives (such as Gaeta or Kalamata), rough chop
• 2-3 tablespoons capers, drained
• 1/2 cup cooked white beans (optional)
• salt and pepper, to taste

1. Heat the olive oil and the butter over medium-medium high heat. When the oil shimmers, add the onion and fennel and cook 4-5 minutes, or until golden brown. Add pepper flakes, anchovies, and garlic and cook, stirring, until the anchovies dissolve. Stir in the tuna.
2. Increase the heat and add the wine and cook until almost all reduced. Stir in the parsley and the tomatoes and return to a simmer.
3. Add the olives and capers and simmer about 5 minutes. Season to taste with salt and pepper. (If you're using the white beans, add them in the last minute or so of cooking, just long enough to heat through.) Serve with pasta of your choosing, though it's particularly delicious over spaghetti squash.
