A favourite at my home is Moroccan style tuna pasta salad. Quick, easy, cheap and good.
What you need is:
Pasta (any type will do, but I prefer the butterfly or screw shapes)
1 tin of tuna
1 medium yellow onion
a few spoons of mayo
salt
pepper
dried chopped mint
dried ground ginger
Start cooking the pasta as the instructions on the box.
Finely chop the onion and put it in a medium sized pot with some olive oil. Cook until translucent.
Drain the tuna, break it up and place in the pot with the onion, continue to break it up more with a spoon or spatula while stirring it in with the onion.
Add the spices. Go easy on the mint and ginger at first til you get a feel for it, maybe about 1/2 a teaspoon.
Turn off the heat.
Now for the tricky part, you need to add the mayo but want to avoid it splitting if it gets too hot. Add 2-3 tablespoons full of mayo to the mixture and mix well in, keep on stirring and allow the residual heat to heat up the mayo.
Pour the mixture into a large serving bowl along with the drained pasta and mix. Serve while hot.
Now, I'm not a fan of cold pasta, so you can make the last part easier by adding the mayo into the mix bowl and not the pot, but then the meal will be cooler.
