I found this recipe this morning on the www.mccormick.com website. "This creamy casserole can be made a day ahead, refrigerated and then baked just before dinner. Using frozen vegetables makes this dish a cinch." Flavor Variation: Substitute 1 teaspoon McCormick® Lemon & Pepper Seasoning Salt and 1/2 teaspoon McCormick® Basil Leaves for the Italian Seasoning.
