Pasta al Tonno

What the traditional version is
A fast pasta sauce made by frying garlic, chilli, capers and black olives in olive oil, then adding a tin of tuna with its oil and some tomatoes. Served with long pasta and absolutely no cheese.
What changed, and what each change costs
200g of tuna in oil down to 400g of tuna in spring water
Tuna in oil is saturated with fat. Spring water tuna is pure lean protein. By ditching the oil you save hundreds of calories, which leaves room to use 400g of fish instead.
What it costs you. Tuna in spring water is drier. You've got to flake it into the tomato sauce right at the end so it warms through without turning to sawdust.
60g of olive oil down to 15g
Because you aren't using the oil from the tuna tin, and you don't need a huge glug in the frying pan either. A small splash is plenty to fry the garlic and bloom the chilli.
What it costs you. You lose that rich, oily mouthfeel that coats the pasta. The sauce feels slightly sharper and more acidic, but the capers and olives carry the flavour just fine.
100g of dried pasta a head down to 80g
You've got 100g of tuna per person now. The plate is going to be incredibly full, so the missing 20g of pasta won't be noticed.
What it costs you. Less carbohydrate, which is the only real cost. The fish completely takes over the bulk of the meal.

The method is in the book
This is the perfect midweek dinner. You get a massive portion, a sharp and punchy sauce, and a colossal hit of protein for very little effort. The original oil-drenched version is richer, but this one leaves you feeling fed rather than sluggish. I make this at least twice a month when I can't be bothered to go to the shops.
