3 cups vegetable stock, heated up

1 teaspoon dried thyme  
14-16 oz. solid white tuna in water, drained, and flaked into 1” pieces

To Make the Sauce:

3. When thickened, add the milk. Whisk again.

5. Take off heat and whisk in half of the salt (1 ½ teaspoons), lemon juice, parsley, and thyme.

2. Turn out into casserole dish. Refrigerate or bake right away.
