Encouraging green eating

How do you get older people to eat their greens? I know, I know. It sounds strange but some of them hate eating vegetables and would rather eat chips. Wouldn't we all? But how do I encourage any of them to eat veg? Curried, in lasagne, salads of fish and chicken 'garnished' with a number of leaves, lots of dressing on big colourful salads and the promise of melon within the subtle flavours of a salad. Gem lettuce leaves, rocket with tuna, tomatoes, avocado, cucumber. Then drizzled over with virgin olive oil, balsamic vinegar and some garlic crutons maybe?
