Fresh breadcrumbs and Parmesan cheese create a savory crumb topping.
Place bread in a food processor; pulse 10 times or until coarse crumbs measure 1 cup. Combine breadcrumbs, cheese, and parsley in a small bowl; set aside.
Combine 3 cups boiling water and sun-dried tomatoes in a bowl; let stand 10 minutes or until soft. Drain tomatoes over a bowl, reserving 1 cup liquid.
Heat oil in a nonstick skillet over medium-high heat. Add onion, rosemary, crushed red pepper, and garlic; saute 3 minutes. Add tomatoes and reserved 1 cup liquid. Bring to a boil; cook 7 minutes or until most of liquid evaporates. Add 1/2 teaspoon salt, black pepper, and beans.
Preheat oven to 400°.
Combine 4 cups boiling water, 1 teaspoon salt, grits, and butter in a large saucepan. Cook 8 minutes over medium heat, stirring constantly. Pour grits mixture into an 11 x 7-inch baking dish coated with cooking spray. Spoon tomato mixture evenly over grits; top with breadcrumb mixture. Bake at 400° for 20 minutes or until golden.
