1/2 cup sour cream

1 cup shredded sharp cheddar cheese, divided
1/4 cup grated Parmesan cheese
1 teaspoon Dijon mustard
1/2 teaspoon dried thyme
1/2 teaspoon salt

Instructions
Preheat the oven to 375°F (190°C).
Heat the olive oil in a large skillet over medium heat.
Add the chopped onion and cook for 3-4 minutes until softened.
Add the minced garlic and cook for another 1 minute until fragrant.
Add the chopped cauliflower and broccoli florets to the skillet and cook for 5-6 minutes until tender but still crisp.
Remove the skillet from heat and transfer the cooked vegetables to a large mixing bowl.
Add the drained tuna, sour cream, mayonnaise, half of the shredded cheddar cheese, Parmesan cheese, Dijon mustard, dried thyme, salt, and black pepper to the bowl.
Stir all ingredients together until well combined.
Transfer the mixture to a greased 8×8 inch baking dish and spread evenly.
Sprinkle the remaining shredded cheddar cheese evenly over the top.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
Remove from the oven and allow to cool for 5 minutes before serving.
