Spicy Tuna Pesto Pasta

I’m a big fan of “pantry-friendly” recipes.
Though I have to admit that it’s kind of a vague term, since it doesn’t account for much of the diversity that influences what fills our cupboards.
But I’m pretty sure that in almost every household you can find a can of tuna, an onion, some tomato paste, olives, parsley, and oil.
That’s really all it takes to make this incredible Spicy Tuna Pesto Pasta.
