On a more serious note...
I like to keep things simple... Let the true flavours of the veg shine through...
Sounds a bit of a cliche but you can't beat a good old Caprese salad when in Italy. So speaks a man who thought he didn't like tomatos
The secret to a good homemade pizza sauce is to add a few drops green tabasco (seriously.. try it

)
While i'm on the green tabasco front... Veggie chilli. One of the few times I use 'fake flesh' (quorn mince). Works great bulked out with a can of chickpeas. Finish with a squirt of tomato ketchup for extra richness
God I'm starving now... I'm seriously considering Thai curry for breakfast.
