Leftover grilled asparagus

Both of your ideas are great! Another thought is a frittata, cut into slices.

I'd make either frittata or sformato and serve as an appetizer. Do let us know what you make.

could go into a cold sesame salad with soba noodles

Slice a red onion or two (or more, depending on how much asparagus you have) into rounds about ¾" thick, and grill them just until they start to soften. Then cut the rounds into quarters, cut the asparagus into bite-sized pieces, and toss the onion pieces with the asparagus with some olive oil, balsamic, and a generous sprinkling of parmesan. Season w/ S&P to taste.

Probably a bit close (or past) decision time, but I’d serve it as is with a quick romesco (almonds or other nuts, jarred roasted red peppers, bread or breadcrumbs, smoked paprika, vinegar, olive oil).

Hi Dave, once again, I'm late to the party. Glad you found a delicious solution. But let me add two asparagus preps I've made in the past few days before the season ends.

First, I want to show my friend's method of grilling. The asparagus tips are away from the hottest flame so that they don't get overcooked or burn.

This grilled asparagus was served room temperature drizzled with good walnut oil then topped with toasted and chopped walnuts, fresh grated lemon zest, salt and halved cherry tomatoes for color. It was intentional to not add any acid to the dressing to let the full richness of the walnuts dominate. The lemon zest added a little bit of lift.

This one used poached asparagus, but grilled is better and should be served warm. Painted on the plate is David Chang's miso butter (2:1 of softened unsalted butter:white miso paste, plus a few drops of rice wine vinegar). On top, duck eggs poached three minutes to have runny yolks and sprinkled with shichimi.

Pro tip for peeling asparagus: Lay the asparagus on your cutting board to steady it to be able to peel a thinner layer.

I am too late, but for next time some ideas:
Goat cheese and asparagus Paninis
Wrap in puff pastry with cheese and bacon
Cream of asparagus soup
Asparagus quiche

For some reason my photo didn't load when I posted last time. Here's a picture of the romesco and the asparagus (and a bit of eggplant).

If you did not over cook them on the grill you have many options.

If you did over cook them on the grill...they should have been tossed... before ever serving them.

Grilled asparagus can go from fantastic to horrible in less than two minutes of over cooking.

Risotto

A delicious combination is the sweetness of asparagus and the saltiness of feta cheese. Make a quiche using eggs, milk, and about 2/3 shredded Swiss cheese and 1/3 crumbled feta cheese (feta is too salty to use all feta). Cut your leftover grilled asparagus into bite-size pieces, lay it in the partially baked crust, and pour the eggs-milk-cheese over it. Bake. You will not believe.
