  • 1 small onion, finely chopped
  • 3 cloves garlic, smashed and minced
  • 1 tsp vegetable oil like olive
  • 6 Vegan sausage patties, crumbled or chopped Either Gardein or Morningstar is fine. Morningstar makes vegan sausage and grain patties -- be sure to use that, and not the one in the green package that contains egg whites.
  • 1 cup finely chopped mushrooms (crimini or button or portobello are all fine)
  • 16 oz frozen veggies. I used a mix of green beans, wax beans and carrots. You can choose your own, including corn, green peas, and green peppers.
  • 1 tsp dry sage or thyme
  • 1/4 cup all-purpose flour (sub rice flour if glutenfree)
  • 2 cups unsweetened cashew or almond milk
  • Salt and ground black pepper to taste
  • 4 cups (approx) tater tots to top your skillet


  • Preheat the oven to 350 degrees Fahrenheit.
  • Heat the oil in a 12-inch cast iron skillet. Add the garlic and onions, season with salt and ground black pepper, and cook over medium heat until soft but not brown.
  • Add the sausage and stir for a couple of minutes until it starts to brown.
  • Add the mushrooms and stir well. Saute for a few minutes until the mushrooms start to soften, then add the sage or thyme and the flour and mix well. Cook, stirring, for another couple of minutes.
  • Add the frozen veggies, mix, and then add the nondairy milk. Stir frequently until the mixture just comes to a boil.  Add more salt and pepper as needed. Turn off the heat.
  • Arrange the frozen tater tots on top of the veggies. You can make a simple but appealing design, like I did, by arranging the tots in concentric circles. 
  • Place the skillet in the oven and bake 55 minutes or until the tater tots are golden-brown.
  • Remove the skillet from the oven and let stand 5 minutes before serving.
