I'm no expert, but you can usually get away with some nice plating and a few colorfull topings. Look at a curry for example, it's really tasty, but the curry itself usually looks like an orange/greenish stew (not talking about japanese curry here) what makes it pop in photos is the cilantro added last minute or the stzrk contrast with som white rice.

In the end, you might as well post your "sploodge" every now and then. It's not like the sub is drowning in content and you always get nice tips out of it ;)
