Prep: 10 min., Cook: 20 min. This is a robust, meatless recipe that you can prep in advance. Start by cooking the vegetables. If you make the vegetables a day ahead, cook them a few minutes less to ensure they don't overcook when they're reheated.
Bring first 3 ingredients to a boil in a large saucepan over medium-high heat. Gradually whisk in grits; return to a boil. Reduce heat to medium-low, and simmer, stirring occasionally, 10 to 12 minutes or until thickened.
Whisk in cheeses and pepper until cheeses are melted. Spoon Seasoned Vegetables evenly over grits, and serve immediately.
