Easy pasta

I came back from Dubai loaded with spices and seeds: coriander, curry mixes, pine seeds, burghul, etc. In fact, my kitchen cabinet smells like a spice souk now!
As you know, I love simple and quick recipes (who doesn't?) so, since I have a big box of pine seeds I decided to try a Castelraimondo classic (that would be a recipe I learned to make while I was living in Castelraimondo), pasta with rucola, tomato and pine seeds, so simple but so tasty and healthy.



Spaghetti with rucola, tomato and pine seeds

Ingredients (serves 2)
200 gr. spaghetti
14 cherry tomatoes
A handful of arugula
A handful of pine seeds
A spicy pepper, dried
Half an onion, diced
Salt
Olive oil
Pepper
Optional: a can of tuna

Cook the pasta in boiling salted water for the time written in the pasta package. In the meantime, fry the onion and the spicy pepper together with the olive oil (be generous with the oil) in a pan, after a couple of minutes add the pine seeds and let them cook for 2 minutes before adding the tomatoes, diced and salted. Let it all cook for 5 more minutes and then turn off the stove.
If you want you can add a can of (drained) tuna, if not, when the pasta is cooked, turn back on the stove at low heat, drain the pasta and add it to the pan together with the arugula, previously rinsed and chopped. Mix for about a minute, add some fresh ground pepper and serve.
If you didn't add the tuna, you can sprinkle some grated ricotta salata.
