Anything that's gluten free.
Roasted courgette chunks in olive oil and marjoram, olives, pickled chilli garlic, peppers, chargrilled artichokes, olives, still warm from the sun chunks of massive tomatoes in olive oil, garlic, sea salt, thyme, chilli and lemon juice/sumac, jagged pieces of little cucumbers, proper cheeses made from Ewes' and Goats' milk with herbs/sumac/more olives, watermelon, charred pineapple and thick Ewes' milk yoghurt with pomegranate molasses, yoghurt with walnuts and dates, lightly charred figs with yoghurt and molasses and thyme, GF flatbreads with sesame seeds and seasalt, charred and raw radishes (charred with the leaves & seed pods), a make-your-own charred fruit salad that includes lemon/lime/blood oranges and raw fruit, tabbouleh but with quinoa instead of cracked wheat and with proper quantities of herbs and olive oil, not homeopathic doses of them. Sweetcorn (cobs sliced into manageable pieces) with garlic chilli butter and/or mango chilli dressing and more sea salt.
I'd also be hoping for barbecued lamb or chicken (garlic, vinegar, sugar, lemon, chilli, herbs, olive oil) and possibly fish like GF whitebait, rather than sausages and burgers.
Reality is probably more sat with a tub of homemade coleslaw (shredded red cabbage, carrot, onion, sea salt, mayonnaise, splash of vinegar, pepper and left to marinate for a couple of days) and wishing the jacket potato hadn't been microwaved but had been sitting in the embers of a barbecue for hours to go all fluffy and crispy.
