This is something I often eat as a snack. You pour some oil on a plate and dip some bread (preferably not the sweet fake bread common in the anglosphere, that stuff is vile, it should at least have a crust) in it and sprinkle some salt to taste on top.

It is extremly quick, very cheap, vegan and somewhat healthy. I also like it because i can get a lot of calories very quickly as i tend to eat too little.

This also works with salad dressings and all kinds of vegetable oils and sauces really, but i like the taste of olive oil and it is common everywhere and also healthier .
