Get a big bag of basmati or jasmin rice and get a rice cooker. Where I live a bag of jasmin rice is 36 euro for 18 kilo. You can eat rice with omelettes, wok chicken, shrimp and vegggies or what not, next day make fried rice.
Tons of video's on youtube with people sharing their home made rice dishes.
Edit: A wise man once said “red beans and rice, I could eat a plate twice”
