Hazırlanışı
1Bring a large pot of lightly salted water to a boil. Cook lasagna noodles in the boiling water, stirring occasionally, until tender yet firm to the bite, 8 to 10 minutes. Drain. Cut noodles in half crosswise.
2Meanwhile, melt margarine in a large skillet over medium heat. Add garlic; cook until just fragrant. Stir in flour until no lumps remain; gradually stir in milk. Season with thyme; simmer until thick. Remove sauce from heat.
3Grease a 9x9-inch microwave-safe glass baking dish. Layer noodles, sauce, asparagus, ham, and mozzarella in the prepared baking dish; repeat layers twice more, starting each layer with noodles and finishing with mozzarella.
