0 to use one thing instead of another:
The original recipe called for sesame oil instead of olive oil but sesame oil is expensive so I subbed out olive oil.
We're in Atlantic Canada where we can't get any good cotija or queso fresco, so we subbed out some local feta.
If even a small percentage of US drivers subbed out their big bad cars with one of these, the country would save boatloads of oil.
In a super efficient model, you would sub out all work except for book keeping, inventory management and strategic management.
We could sub the whole thing out and get somebody else to make them.
