What type of food might an organism that lives its entire life in interstellar space eat?

I was thinking of an organism that lives its entire life in interstellar space

• It eats, defecates, moves, grows, ejects eggs, attracts mates, and has sex in interstellar space.
• It has skin that pressurizes its insides so that its insides are pressurized even when the organism lives in the vacuum of space.
• It has thrusters on its back that it can eject fuel out of to change its velocity.
• It is capable of accelerating to 50% the speed of light relative to the rest of the galaxy in 3 months allowing it to cover astronomical distances in search of food and mates.
• Its eyesight is so good that it can see an object the size of Saturn from as far as Earth with as much detail as a human seeing a baseball at a distance of 0.1m.
• It has bioluminescence that allows it to be seen by potential mates.

What type of diet would be most efficient for this organism to have considering that it would have to get all its food from the vacuum of space?

Also: How might its digestive system evolve to process food that it finds and eats in interstellar space?
