What do you need meat for? Awesome bolognese sauce with tuna

Today was one of those days where I opened the fridge door and, at first glimpse, could not see anything much I could cook with.
I was hungry and not about to give up, so I started with the basics and I discovered a great bolognese sauce with capers and tuna.
Served hot with spaghetti, it tasted amazing, was done in 10 min and all from scratch.

For 2 people you will need:

3 cloves of garlic, sliced and diced
olive oil
1 can of tuna
onions, optional
soy sauce
capers
half a can of sliced tomatos, or 4tbs tomato ketchup
salt, pepper

Heat up a pan. Add garlic in to sizzle a little. Be careful to put in the other ingredients soon as to not roast the garlic too much.
add 1 tbs of capers and the tuna and saute for 1 min.
Add 4tbs each soy sauce and sliced tomatos or tomato ketchup.
Put cooked spaghetti on a plate, sauce on top and drizzle parmesan cheese.
Done. And it tastes delicious.
