My guess is that the flavour may not be that great, but since you're using it for cooking rather than to splash over a salad (when flavour is paramount) you'll probably be ok.
Another easy dish for nervous first time cooks is a stir fry. You can either make your own sauce or buy one of those Blue Dragon sachets (they're about 90p) from the International aisle. The simplest accompaniment would be noodles which you can get from the same bit of the supermarket. Pick what meat you want and chop that up very finely. Fry that at a high heat first for a few minutes until it browns and then add a selection of finely chopped veggies (the noodles can be cooking while you do this). After a minute or two add the sauce and heat through. Drain your noodles and then mix in with the stir fry. And voila, you have dinner.
If you're going to be cooking frequently and want to learn, then I recommend getting hold of a book called 'Appetite' by Nigel Slater. He gives loads of recipes with several variations but they are all simple and the explanations given mean that you can branch out and start experimenting on your own, too.
