This grilled halloumi sandwich packs in some of the season’s best flavors: juicy heirloom tomatoes, fragrant basil, tangy pickled onions and warm, golden halloumi cheese tucked between hearty bread slices.
Unlike many cheeses, halloumi has a high melting point, allowing it to develop a crispy, caramelized exterior while remaining soft and chewy inside. It also provides protein and calcium.
The tomatoes pack in vitamin C, potassium and lycopene, a plant compound with antioxidant properties. Whole grain bread adds fiber, which supports digestive health and helps keep you feeling satisfied.

Here are SEO-friendly, reader-focused FAQs that complement the recipe while naturally incorporating relevant nutrition information.

FAQ
- What is halloumi cheese? Halloumi is a semi-hard cheese traditionally made from sheep’s and goat’s milk, although some varieties also contain cow’s milk. It has a mild, salty flavor and a unique texture that becomes crispy on the outside and soft and chewy on the inside when grilled.
- Can I make this sandwich without a grill? A nonstick skillet, cast-iron pan or grill pan works well for cooking the halloumi. You can also toast the bread in a toaster or under the broiler.
- Can I use a different type of bread? Whole grain bread adds fiber and nutrients, but sourdough, ciabatta or multigrain bread also work well. Choose a sturdy bread that can hold the grilled cheese and juicy tomatoes.
