I am making a tri tip on the grill with roasted fingerling potatoes and coleslaw. Can you recommend another side dish to accompany this meal

I am obsessed with CORN right now so I would suggest a corn, cherry tomato and avocado salad, fresh basil vinaigrette (spelling? hmm) - lightly char the corn first. Maybe add some green onion. Use the cobs to make corn broth.
yum

I'd second the tomato suggestion. I think it would balance things out nicely. You can do something as simple as slicing them and tossing with oil, balsamic, salt and pepper.

I'm sitting down relaxing after a beautiful tri tip done on the charcoal grill. I recommend a fresh herb chimichurri sauce. Simple sliced heirloom tomatoes, gently fried in olive oil with a teaspoon or two of minced garlic from the Jerusalem Cookbook. Texas toast. Corn on the cob. Potato salad. Peach pie. Belvedere Martini. Feeling good

I am really into ratatouille right now. I've made Francis Lam's Weapon-worthy recipe twice and it's amaze-balls. However, it's quite lengthy. There are other recipes for it on this site that are much quicker.

It's tomato season, so I'd find some really sweet ones and do a simple tomato salad - or maybe a classic tomatoes Provencal (tomatoes baked with a garlicky crumb topping.) Patricia Wells' recipe - very easy and delicious: http://www.nytimes.com/recipes/3375/tomates-a-la-provencale-baked-tomatoes.html
