Literally made some last night. Made some flat bread (flour, baking powder, yogurt, olive oil), browned the halloumi, smeared some store bought mango chutney and a dollop of yogurt on the bread, topped with the halloumi and fresh fresno chilis. So delicious. A riff off a Jamie Oliver recipe. Not the healthiest (apparently fiber is the enemy) but very filling and feels quite special for a quick easy meal!
Grilled pineapple is really good, and you can make it savoury/sweet or just sweet depending on your tastes. I usually prepare it as a siding for pork, but you could easily adapt it to not use meat; for example, in skewers alongside pepper and onion.
I've always been intrigued by some of these 'unusual' grilled items such as cabbage and fruits. Really need to just try it out and see if I'll be pleasantly surprised!
I love grilled veggies in general though. Zucchini and eggplant are my goto.
I made a grilled veggie board with summer squash, bell peppers, baby bok choy, tomatoes, and haloumi for r/52weeksofcooking boards theme week and it was delightful.
