<p>Grilled asparagus is great at room temp. I just roll it in a little olive oil, coarse salt, and black pepper. Actually, I sometimes serve it as an hors d’oeuvres. Essential that it get a little blackened. :)</p>
<p>Asparagus blanched until just tender then shocked in ice water is also great cold with an Asian sesame/ginger/soy dressing such as that suggested by dragonmom. For this purpose, I cut it into pieces in the Chinese way: make an angled cut, rotate, make another angled cut, and so forth.</p>
<p>I’m going to have to try that roasted kale. I keep reading about it, I love kale, and I’m always looking for something I can eat to satisfy the urge for a salty snack that is very low carb and not too calorific. One can eat only so many almonds without blowing the calorie budget.

<p>Another thing that is good at room temp is a corn salsa/salad made with black beans, diced red pepper, scallions, minced jalapenos, and so forth. You could just add some good spice salsa as the dressing.</p>
<p>At parties, I sometimes serve little cups of cold pureeed vegetable soups as an hors d’oeuvres. I go for a variety of colors: beet/red pepper for pink, carrot coriander for pale orange, curried asparagus for green, etc.</p>
