Marinated Anchovy Sandwiches With Tomato-Onion Sauce Recipe

• 3 tablespoons olive oil
• 2 plum tomatoes, cut into 1/4-inch-thick wedges
• 1 small yellow onion, peeled and thinly sliced from pole to pole (about 1/2 cup)
• 2 medium garlic cloves, thinly sliced
• Kosher salt and freshly ground black pepper
• 1 tablespoon sherry vinegar
• 2 (6-inch) crusty rolls, such as ciabatta, halved
• 2 tablespoons mayonnaise
• 4 ounces marinated white anchovies
• 1/4 cup packed cilantro leaves

1. Heat oil in large skillet over medium-high heat until shimmering. Add the onion, tomatoes, and garlic and season with salt and pepper. Cook, stirring occasionally, until the onion and tomatoes are softened and the mixture has a sauce-like consistency, about 5 minutes. Stir in the vinegar and cook, stirring, for 1 minute longer. Remove from heat.
2. Spoom half the tomato sauce on 1 side of each roll and top each with half of the anchovies. Sprinkle with cilantro. Spread 1 tablespoon mayonnaise on the remaining roll halves, then top the sandwiches and serve.
