Haricot Vert, Purslane & Swiss Summer Panini

A dear friend invited me to raid her garden over the weekend and I was there almost before I hung up the phone. After a lovely evening filled with berry juice-stained fingers, floppy hats, the warm wink of fireflies and the thunk of beans hitting the bottom of a new bucket, I came away with quite a bounty, including a bit of a brand-new-to-me edible weed, purslane. Her Turkish beau pointed out its presence on her property - I gather it is greatly enjoyed by Turkish folk (with yogurt, especially). I like it; it has a slight mucilaginous quality but it is succulent (and IS a succulent!), with a lightly sour, cress-like flavor. A perfect addition to salads, or in this case, a crisply verdant summer panini with beans also plucked from the garden. However, if you don't stumble across it outdoors, you can always sub arugula or watercress.

This sandwich is inspired by the haricot vert panini on the menu at my beloved Tired Hands, although I must confess that even though it has intrigued me for months I have never ordered it because their meat ones are SO GOOD that I'd never dream of eating anything else there. However, my version has me convinced that it's a true contender with the meat'uns, especially in these summer months where something lighter is better. Sometime I'll have to actually order my inspiration while I'm sipping a delicious saison and see how it stacks up!

Haricot Vert, Purslane & Swiss Summer Panini
Makes 1 sandwich

*About 1 1/2 tablespoons butter, divided

*1 teensy shallot or 1/2 of a small sweet onion, sliced thinly

*1 big handful of haricots verts, trimmed & blanched (briefly, like 10 seconds max)  

*1/4 cup purslane leaves + a few extra tender sprigs

*2 slices hearty bakery bread

*4 slices of really good Swiss cheese

*Your favorite fancy Dijon mustard, about a teaspoon & a half
*2 tablespoons good EVOO
*2 teaspoons lemon juice
*Leaves from a few thyme branches
*S&P

Whisk together the mustard, evoo, lemon juice, thyme leaves and pinches of S&P, set aside. In a skillet, melt a pat of butter with a drizzle of oil over medium low and add the shallots. Sprinkle with a pinch of salt and saute for a couple minutes before adding in the beans. Saute a few minutes more then add the purslane leaves and remove from heat. Toss with the mustard vinaigrette. Season to taste.

Brush one side of each of the bread slices with a bit of the other tablespoon of butter (melted or room temp), then assemble the sandwich by smoothing a thin layer of mustard on one slice, then top with half the Swiss, the bean-purslane mix, the reserved sprigs of purslane, and then the rest of the cheese. Press the sandwich in a preheated panini maker for a couple minutes until the sandwich is toasty and the cheese has oozed. Cut 'n eat!
