Fact: girls love it when you make a bit of effort in a relationship, no matter how long you've been together. So you can't really go wrong by giving some home cooking a go. Best-case scenario, you make an awesome meal that she loves and thanks you for in the bedroom. Worst-case scenario, you burn everything and order a pizza but she still serves up dessert in the sack because what you attempted was "so sweet". This is not about what you like to eat, remember. You can always grab a burger later on...
