I had an extremely busy weekend, and was truly excited to have a Monday night all to myself. I didn't feel like shopping, so threw this together out of my pantry. Seriously delicious.
Bring a large pot of water to the boil, and put a large frying pan on to heat.
Chop the sage and garlic together, combine with lemon zest, fresh ground black pepper and kosher salt in a small dish.
Drain the garbanzo beans.
When the water boils, add the frozen chopped spinach. When the water boils again, add the pasta. Boil for about 5 more minutes, then drain. The rest of the steps happen whilst boiling and draining.
In the meantime, add the tuna in it's oil to the pan, breaking up the chunks with a wooden spoon. Add the sage/garlic mixture and saute briefly. Add the garbanzo beans and allow to simmer, stirring occasionally.
Chop the tomatoes and juice the lemon, add them to the tuna mixture and saute -- basically you want to soften the beans a bit, warm the sauce and incorporate the flavors.
After draining the spinach and pasta, and when the "sauce" is ready (taste!) toss them together.
