How to Make It
In a medium saucepan of boiling water, cook the cranberry beans until tender, about 20 minutes; drain.
In a large bowl, whisk the mustard with the vinegar. Gradually whisk in the pecan oil and the 2 tablespoons of grapeseed oil. Whisk in the shallot, tarragon and lemon zest and season with salt and pepper. Add the warm beans to the dressing and toss.
Preheat a grill pan. Lightly brush the zucchini with oil; season with salt and pepper. Grill over high heat, turning once, until the zucchini is crisp-tender, about 2 minutes. Transfer the zucchini to the beans, add the mint and toss. Mound the zucchini on plates, top with the cheese and pecans and serve.
