cheap thing to add to rice?

what's the cheapest thing I can add to rice to make it taste nice? right now I'm using cans of ratatouille which cost too much (1,03€) for my budget, I need to eat a full meal for 1,5€-2€

White Rice is highest on the glycemic index and is even worse than eating sugar straight with a spoon.  You will most like develop Type II Diabeetus if you continue to eat white rice.  You could switch to brown rice, but you're too lazy to make it.
