Firstly, boil the pasta in salted water as per packet instructions.
Now, finely dice the shallot, crush the garlic, quarter the tomatoes and slice the olives (stones removed).
Heat a large non stick pan with olive oil, add in the shallot, crushed garlic, tomatoes, olives, chilli flakes, pinch of salt and pepper and fry together until softening, roughly 5 minutes.
Now add the drained tuna, roughly chopped parsley, lemon juice and 4 spoons of pasta water (directly from the boiling pasta pot) and fry for a further minute.
Finally, drain the pasta and add into the pan and stir together. Season with salt and pepper to taste and serve.

Notes
Step-by-Step Photos: My blog post includes helpful step-by-step photos to help guide you through making this recipe.Substitutions & Variations: I have included a list of these in the post above.To Store: Store in an airtight container in the fridge for 3-4 days. Reheat in a pot/pan over a low heat until piping hot or in the microwave. You may need to add some water to loosen the sauce.To Freeze: You can freeze leftover tuna pasta in an airtight container for up to three months. Defrost in the fridge and then reheat in the microwave or on the stove.Tip 1: If you use tuna with oil, use that oil rather than the olive oil in frying up the ingredients!Tip 2: Be cautious of how much you stir the pasta once the tuna is in. Too much stirring will break the tuna chunks into smaller and smaller pieces.Tip 3: If you prefer your tuna spaghetti more on the creamy side, try adding cream, Greek yogurt, sour cream, cream cheese, or mayonnaise.
