Toss 4 thinly sliced summer squash or zucchini with 1 tablespoon kosher salt; let sit 20 minutes, then rinse and pat dry. Chop 2 shallots, 1/4 cup each parsley and mint, 3 tablespoons olive oil, 1 tablespoon thyme, 1 seeded red jalapeno and 1 teaspoon lemon zest in a food processor; toss with the squash and 3/4 cup grated gruyere. Arrange evenly in a baking dish; top with 1/4 cup more cheese. Bake at 400 degrees F, 35 to 40 minutes.
