Any ideas what I can make for my dinner tonight?

I`m studying just now and I`ll be going home at about half nine for some dinner I`ll be stopping at the local somerfield on Byres rd. which is usually either full of crap or has empty shelves, any ideas of something a bit different i can make myself? i`ve got a budget of about �6 mibbees stretching to �8. thanks for all suggestions in advance apart from the obligatory ones that`ll tell me to eat sh1t and die etc etc !!
