Found myself put in charge of minding a house and found a big bag of dried basil and some sesame oil. I had some tomato puree with me for doing other things so I went straight into trying to do a red pesto and I'm happy with it. This is what I'm using.

Basil
Taragon (Smelled alright for the mix so I added that along with your run of the mill mixed herbs)
Sesame Oil (Add's a lovely 'rustic' flavor.)
Vegatable Oil
Onion powder(Another item I found in the house, not sure if its a star ingredient or not)
Salt/Pepper

Anything else can I add?
