I made chicken fajitas the other night, and served them with a Sainburys Basics Rose - £2.49. It went down very well and a good time was had by all!
Seriously, you've been given some good advice here. I'm a big fan of tasting sessions, whether they're organised for you or you do it yourself. It's the best way to decide what your own personal preferences are. I can drink any wine except dessert wines (too sweet and syrupy for me) - cheap red wine is fine by me. But for preference I like a good Rioja. Rioja Gran Reserva if given my druthers. I'll pay about £20 for it and really enjoy the taste. Above £20? I wouldn't know - in fact I'd rather not know because if it was amazing it would spoil the wine I could afford. It's my decadent treat - I don't drink it to get drunk and I savour every mouthful. Haven't had it for a while
I won't drink cheap champagne though. I'd rather have a decent Cava. Well - I say I won't drink it... if it's free I will

But it's usually given out at work occasions, and if I'm there it means I have a job, and if I have a job I have the money not to salivate over free booze!
Have fun with it.
There is no right and wrong, it's all personal taste, like finding your way around the world of cheese. Some people are only ever going to enjoy processed slices by Kraft, some will travel miles to get just the right Camembert. If what tickles your fancy is squeezy cheese then just go with it - finding out you don't have expensive tastes doesn't make you plebian, it just saves you money.
