Divide the tuna over the pasta and stir through (not too rough; otherwise, the tuna will break up too much).
¾ pound canned tuna
Serve.
NOTES
1. Pasta: Use Penne, tagliatelle, or fusilli.2. Tuna: Use canned tuna. You can buy this with olive oil, sunflower oil, or water. The end result doesn't matter much, but tuna in water is slightly slimmer.3. Tasty: Add some extra basil for an Italian taste.4. More vegetables: Add a handful of spinach to the sour cream sauce.5. Vegetarian: Replace the tuna with grilled vegetables such as zucchini or eggplant. Or replace it with fried mushrooms.6. StorageLet the pasta cool quickly to room temperature.
Refrigerator: Store, covered, in the fridge for up to 2 days.
Freezer: Because you have added sour cream, it is better not to freeze this.
Reheat: Add two tablespoons of water and heat over medium heat in a skillet while stirring. Heat until hot.
