The weather this past Saturday was so gorgeous that it absolutely called for my first farmer’s market haul of the season. I came home with spring asparagus, peas, yellow squash and some beautiful crisp baby arugula. Now to turn them all into dinner!

I haven’t made quiche in a while so I thought it would be a good way to gather all the vegetables into one dish. But I also wanted something with a bit more oomph. Experimenting with different condiments is a great way to interject extra flavor and one of the easiest oomph additions is mustard.

I grabbed my fridge staple, Maille Dijon Original Mustard, and got creative with the pastry dough. I already knew adding it to the egg base would be great but I was hoping for a crust with an extra savory note. Success! My standard savory butter crust with a touch of olive oil and a big dollop of the mustard got me the exact burst of flavor I was after.

I served the tart with the fresh arugula on top, dressed in a mustard vinaigrette, of course. This dish definitely didn’t last long in my house and now I really want to make another one. Enjoy!
