Sorry, I am not convinced. Someone who can't find umami flavour in plant based food easily isn't a good cook. You perhaps reach a satisfying result when you stay in your area of expertise, which is cooking meat based dishes. That might make your job a cook, but it certainly does not make you good at it.

But I ethically feel that eating meat is a good thing

I am very interested in how you argue it's "ethically good" to breed lifeforms just to have them suffer and then eat them.
