Roasted Cauliflower Grilled Cheese: From Prep to Plate

Step 1: Roast the Vegetables
Start by preheating your oven to 425°F (220°C). Slice the head of cauliflower into flat, 3/8-inch-thick pieces. Slice the yellow onion into 1/4-inch-thick rounds. On a roasting pan, toss the cauliflower and onion with 1 tablespoon of olive oil, salt, and freshly ground black pepper to taste. Spread them out in a single layer and roast for about 20-25 minutes, or until they are tender and slightly caramelized.
Step 2: Prepare the Cheese Spread
While the vegetables are roasting, prepare your cheesy spread. In a mixing bowl, combine 1/4 cup of light mayonnaise, 1 minced garlic clove, 2 teaspoons of whole grain mustard, and 2 teaspoons of fresh lemon juice. Season with salt and freshly ground black pepper to taste. Mix well until all ingredients are combined.
Step 3: Assemble the Sandwiches
Spread a generous layer of the mayonnaise mixture on one side of each slice of whole-grain bread. On the non-spread side, layer the roasted cauliflower and onion, followed by a slice of Arla Dofino Gouda and a slice of Arla Dofino Creamy Havarti cheese. Top with a handful of baby arugula before placing another slice of bread on top, spread side facing out.
Step 4: Grill the Sandwiches
In a non-stick skillet over medium heat, melt 1 tablespoon of softened butter. Once the butter is melted and bubbling, add the assembled sandwiches. Grill for about 3-4 minutes on each side, or until the bread is golden brown and the cheese is melting. Keep an eye on them to prevent burning!
Step 5: Serve and Enjoy
Once your sandwiches are perfectly grilled, remove them from the skillet and let them cool for a minute before slicing. Serve warm with your favorite soup or a side salad for a complete meal. Enjoy the gooey, cheesy goodness!

- Accompaniments: Pair with seasonal dips or sauces for a unique flavor experience.
Troubles You Can Avoid
- Overcooking the Cauliflower: Keep an eye on the roasting time to ensure it’s tender but not mushy.
- Uneven Grilling: Make sure to use medium heat to allow the cheese to melt while the bread browns evenly.
- Too Much Spread: A thin layer of the mayonnaise mixture is all you need to avoid sogginess.
- Skipping Seasoning: Don’t forget to season every layer for maximum flavor!
