    From the Test Kitchen

    By filling slices of warm, golden brown sourdough bread with layers of caramelized onion and melty fontina and cheddar cheeses, we’re giving this comfort food favorite a gourmet boost. For a sweet contrast, we’re dressing buttery leaves of lettuce with a piquant mix of fig spread and dijonnaise, plus almonds for a bit of crunch.

    Prepare & caramelize the onion
    1 Prepare & caramelize the onion

    Halve, peel, and thinly slice the onion. In a medium pan (nonstick, if you have one), heat half the butter (you will have extra) on medium-high until melted. Add the sliced onion; season with salt and pepper. Cook, stirring occasionally, 8 to 10 minutes, or until lightly browned and softened. Add the vinegar (carefully, as the liquid may splatter) and worcestershire sauce. Cook, stirring frequently, 30 seconds to 1 minute, or until the onion is coated. Turn off the heat. Taste, then season with salt and pepper if desired.

    Prepare the remaining ingredients
    2 Prepare the remaining ingredients

    Meanwhile, wash and dry the lettuce. Cut off and discard the root end; roughly chop the leaves. Roughly chop the peppers. Combine the chopped lettuce and chopped peppers in a large bowl. Grate both cheeses on the large side of a box grater; combine in a separate bowl. To make the dressing, in a separate bowl, whisk together the fig spread, dijonnaise, and 1 teaspoon of water. Taste, then season with salt and pepper if desired.

    Assemble & cook the sandwiches
    3 Assemble & cook the sandwiches

    Assemble the sandwiches using the bread, caramelized onion, and grated cheeses; season with salt and pepper. Rinse and wipe out the pan used to cook the onion. In the same pan, heat 1 tablespoon of olive oil on medium until hot. Add the sandwiches; loosely cover the pan with foil. Cook 2 to 4 minutes per side, or until lightly browned and the cheese is melted (if the pan seems dry, add a drizzle of olive oil before flipping). Transfer to a cutting board; immediately season with salt. Carefully halve the cooked sandwiches on an angle.

    4 Make the salad & serve your dish

    Just before serving, to the bowl of chopped lettuce and peppers, add the almonds and enough of the dressing to coat (you may have extra). Season with salt and pepper; toss to coat. Taste, then season with salt and pepper if desired. Serve the cooked sandwiches with the salad on the side. Enjoy!
