  • 2 tbsp butter
  • 1 lb cauliflower cut into small florets
  • 2 tbsp olive oil
  • 1 yellow onion chopped
  • 2 cloves garlic minced
  • 1 lb ground beef or ground turkey
  • 1 ½ cups canned whole tomatoes, drained
  • 2 tbsp tomato paste
  • 1 tbsp Dijon mustard
  • 2 cups shredded cheddar cheese
  • salt and pepper


  • 2 dill pickles

  • Preheat the oven to 400°F (200°C) and grease a 9×12" (22 x 30 cm) baking dish with butter.
  • Boil the cauliflower florets in lightly salted water for about 3 minutes or until tender. Drain thoroughly in a strainer.
  • In a non-stick pan, heat the olive oil over medium heat. Add the onion and garlic, cooking until soft and translucent. Season with salt and pepper.
  • Add ground beef, stirring until cooked through.
  • Drain the canned tomatoes and chop into bite-sized pieces. Reduce heat to medium-low, and add the tomato paste, diced tomatoes, mustard, cauliflower, and spices. Once combined, add ⅔ of the shredded cheese, stirring until melted into the mixture.
  • Pour mixture into the baking dish, and add the remaining cheese on top. Bake in the oven for 15-20 minutes, or until golden brown.
