Break the spaghetti to the right size for a salad, cook it until al dente in sufficient salted water, quench, drain and toss in a little olive oil.
While the spaghetti is cooking, drain the tuna and paprika well, pick the tuna, chop the paprika and dice the onion finely. Then put the tuna, bell pepper, onion and chilli sauce (I use 2-3 bottles) with the spaghetti in a large salad bowl and mix everything well. Now just add salt, pepper and paprika / chilli to taste and the salad is ready.
Instead of tomato peppers from the jar, you can also dice 3 fresh peppers and add them.
A great pasta salad! Also tastes good the next day.
