Griddle then add lemon juice and salt (maybe chilli flakes) - broccoli, courgette, green beans
Add cream or cheese - leeks, spinach
Stir fry with garlic and a bit of toasted sesame oil - cabbage, mange tout, snow peas, baby sweet corn, red pepper, broccoli
Add bacon - anything in the cabbage family, cabbage, cavolo nero, brussel sprouts, broccoli. And/or add nuts - toasted pine nuts, flaked almonds, chestnuts all go well
Cut up smallish and roast with spices or herbs - butternut, cauliflower, carrots, parsnips, aubergine. Good with garlicky yoghurt dressing
Got to be honest though I mostly just boil/steam and cover in butter …
