Does it need to be on the table in 5 minutes or just 5 minutes of your time? Because tray bakes can be great - stick chicken on tray, add whatever flavourings, stick in oven and serve with rice/boiled veg.
We love roasted tomatoes so I do big trays of cherry tomatoes or similar (ie no chopping) with olive oil, bit of balsamic, salt and chilli flakes - if they've already had the leaves removed this takes about 60 seconds to prep - with olive oil and whole garlic cloves roasted on slow for about 60 minutes. Made with couscous and feta. But only works if you're then using that hour to do something else.
Cook pasta (then wonder out of the kitchen while it's mostly cooking). Just before you drain it, remove half a cup of cooking liquid and add a bag of baby spinach. Drain. Put back into the hot pot and add a tub of ricotta, some grated parmesan, some chopped garlic, some olive oil and some lemon zest. Stir enthusiastically, using some of the cooking water if necessary. Generous salt, pepper and more parmesan and serve. I haven't done this, but suspect a few strips of smoked salmon through it would work well too.
Sausages in the air fryer are genius and easy. Ready made mash or new potatoes on the boil with other easy veg like frozen peas/corn.
Scrambled egg on toast with smoked salmon.
Burgers with a bagged salad.
We love chargrilled greens - usually tender stem broccoli, leeks and cavalo Nero or some combination. I shove them in pita breads with either:
quick fried steak slices
Fried halloumi.
If Halloumi - when I turn the halloumi over, I add lemon, honey and garlic to the pan and let it caramelise to give a little sauce.
These work well for us also as portable options on the way to football or other sports activities so quite popular.
Similarly, I sometimes use the air fryer to cook crumbed chicken breasts and put those in rolls with lettuce, tomato, gherkins and mayo for an on-the-go chicken burger.
