I eat salads for lunch. You can get amazing salads in if you like, as one poster called it here, chaotic ones.
Great weather for it, quick, can be done in advance and portable.
Use dark leaves instead of standard iceberg lettuce. Spinach, rocket, cress all have lots of flavour. Fresh herbs add a lot too.
Some of my favourites atm:
Green base, tomato, cucumber, radish, fermented onion, topped with mix of yogurt, chooped eggs, chives, parsley, cracked pepper, chili flakes, drop of worcester sauce.
Green base, spring onion, quick pockle raddishes and cucumbers (without the brine), fresh red onion, edamame beans, prawns, hoison.
Green base, red onion, cucumber, roasted pepper, chickpea, feta, parsley, tomatoes, arabic aalad spice, chilies.
Simple tuna salad but with yogurt instead of mayo is so refreshing.
Hot meals
White fish fillet (black pepper on one side and sriracha on the other before you flip it) and veg like tenderstem broccoli and fine beans with bit (or a lot) of amoky chipotle sauce over it. All can be done on one pan.
Another one pan wonder. Salmon, pan fried, lots of black pepper on it. Throw some mangetout beans to it and if you fancy some tenderstem broccoli or brussle sprouts. Add teriyaki to a pan just before it's all done, mix the veg in it and you can quickly reduce it as well like that to pour ovetlr after served. Quick mash, chop potatoes, put in a box, microwave until mashable, then add wasabi. Again. Can be done in 1 pan, plus the box.
