greek salad dressing

i'm forever trying to recreate Panera's greek dressing.
this one is pretty darn good, but still no panera.
don't store it in the fridge, it gets all congealed and gross.



1/2 cup EVOO
2 tsp each: garlic powder, oregano, basil
1 tsp each: salt, pepper, onion powder, ground mustard
5/8 cup red wine vinegar
