Preheat your grill to medium and place the corn and asparagus on the grates. I use a mesh tray to grill my asparagus so I don't lose any through the cracks, remove when corn and asparagus start to brown.

Chop asparagus into 1/2 to 1" pieces

Remove kernels from corn cobs with a large knife

Combine asparagus, corn and diced tomato in a large bowl

In a small bowl whisk together the lemon, mustard and salt, slowly drizzle in the olive oil while whisking

Stir in dressing right before you serve (some like this to marinate awhile, I don't but that's completely to your taste!)

Enjoy!
