Preparation Steps
- Preheat 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 olive oil, salt, and pepper. Spread them out in a single layer and roast for about 20-25 minutes, until tender and slightly caramelized.
- While the vegetables are roasting, prepare your cheesy spread. In a mixing bowl, combine mayonnaise, minced garlic, whole grain mustard, and lemon juice. Season with salt and pepper to taste. Mix well until all ingredients are combined.
- 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 Gouda and a slice of Havarti cheese. Top with baby arugula before placing another slice of bread on top, spread side facing out.
- In a non-stick skillet over medium heat, melt butter. Add the assembled sandwiches and grill for about 3-4 minutes on each side, or until the bread is golden brown and the cheese is melting. Keep an eye to prevent burning!
- Once grilled, remove the sandwiches and let cool for a minute before slicing. Serve warm with soup or a side salad. Enjoy!
Notes
- For a spicy kick, try using pepper jack cheese.
- Feel free to substitute other seasonal vegetables like zucchini or butternut squash.
- Store leftovers in an airtight container in the fridge for up to 2 days.
