I'm not a vegetarian so I ignored those. I imagine that's often true for vegetarian dishes in the US that they're less calorically, with the exception of heavy pasta/cheese/butter dishes.
They also sometimes had salad. But in general the options were on the heavy side. I say this as a person who orders delivery from these apps regularly, and 80% of the time checked spoon rocket's options (and 5% of the time ordered).
