I do a meal we call pesto rice.
Enough rice for however many people. Get that on to cook.
In a pan, mix a whole large jar of pasta sauce with 2 tins of tuna, a whole jar of pesto and a good handful of grated cheese and as much garlic as you like.
Dump that on the rice, give it a stir and it makes a lovely, warming soupy Thing. If you're feeling fancy, put some naan bread on the side of scooping.
Start to finish is 15 minutes.
