Tuna Gravy

1 (6 ounce) can tuna, well drained
2 tablespoons butter
2 tablespoons flour
2 cups milk
Salt and pepper to taste

Preheat 8-inch skillet over medium-high heat.
Melt butter.
Add flour to butter, and whisk together.
Cook for about a minute without burning the flour.
Add milk; whisk together, making sure to stir out all lumps.
Turn heat down to medium.

Meanwhile, crumble tuna and add to gravy.
Season with salt and pepper to taste.
Heat until bubbling.
Simmer for 5-10 minutes, until sauce starts to thicken and gravy is full of tuna flavor.
Remove from heat.
Stir in a little more butter if desired.

Serve over biscuits or buttered toast.
