Easy meals for hostels?

Hey ya’ll, big fan of this community and I’m actually on my first big solo trip ever and I thought I’d turn to you for help! Just had a quick question for the seasoned vets out there; what’s a cheap but tasty meal you can make at the hostel? I know there’s easy stuff like pasta and sandwiches but I’m curious what other cultures do when they’re trying to save money while traveling, budget for groceries below 10 euros right now anyways 90% of my diet is baguette, Brie, and a cured meat sandwich – just because its so cheap and I can’t help but try to save money any chance I get. Don’t know if it helps but I’m in Portugal, Would appreciate any recipes or feedback about my situation, thank you!
