What would you make with the produce I'm about to get in my CSA box?

I am getting my first box from a produce delivery CSA-type service and I'm really excited but also have no idea what to make with what they're giving me. I'm getting:

2 lbs of Creston apples

2 Tarocco blood oranges

lb red beets

3 oz small sunflower sprouts

12 oz portobello mushrooms

1 head green bibb lettuce

1 bunch leeks

I think I'd like to use the portobellos in a pasta dish, so no need to worry about those unless you have a better idea for them. I have never had blood oranges or sunflower sprouts, so I'm interested to try them. Would a salad of roasted beets + blood orange + sunflower sprouts + walnuts with some blood orange vinaigrette be any good?

Please give me all your most creative uses of my produce so it doesn't go bad on me!
