He sounds really picky like me
If he has a favorite green, I would suggest some different types of salads using that green. I think kale is the best to be packed and hold for a while, since even after 6 hours in acid it can still have a bite to it. If he like kale, I suggest you read the kale thread someone made today??!? yesterday. There were some good recipes, and I posted my favorite raw kale recipe there as well. With robust green you can get a strong sauce thus livening the greens up a bit.
Tomatoes with olive oil and herbs are quite easy and good, and hold fairly well.
If he likes sweets with savory, possibly try caramelized carrots - sauté carrots in your favorite oil with some sugar/brown sugar plus a little salt, and maybe a light pepper ( i personally don't like the sweet savory thing, but i know a lot of people LOVE these)
For a fresh type salad I like shaved/julienned carrots, marinated in lemon juice a little oil and some garlic and dill, salt and pepper of course. You could also make this a mixed vegetables salad if you wanna mix your perferred veggies.
I'm watching a movie and my train of thought wandered, so I forgot what else I was gonna say. I can always pull out my folders if you would like some more ideas.
