ADVICE: How to spice up a simple tuna rice bowl

Hello! The title pretty much says it all. One of my favourite simple work meals is literally just:

- A pre-cooked microwave container of white rice
(I buy them in big boxes at HMart/Han Ah Reum/Asian market), and

- A flavoured pack of tuna
(right now it's Target's Good and Gather Sweet and Spicy pack)

While this is cheap, gets me through the day, and does the job, I'm looking for things that can be added to make it more nutritious or exciting, like an added vegetable or seasoning. The only requirements (aside from being delicious and going with the only two ingredients) is that it has to be shelf-stable and single-serving, so I can grab one of whatever it is and throw it into the container with the rice and tuna.

Thanks in advance!
