Tuna and Spinach in Lemon Sauce

In response to a request. This is a nice, simple tasty tuna and spinach casserole, especially if you like lemon. If you choose to use sprinkle it with crispy chinese noodles, it gives it a nice crunch and flavor boost. I got this recipe from a book called New Casserole Cookery.

6. Prepare the sauce by melting the butter over a low heat in a small saucepan and whisking in the flour until the mixture is smooth.

8. Raise the heat just a bit and cook, stirring constantly, until slightly thickened.

12. Sprinkle with the bread crumb mixture and bake for 15 to 20 minutes, until heated through the and the top is browned.
