Can you eat meat during the duration of the fest of unleavened bread
I think you can eat the meat since there is no stated requirement on not being able to. This is based on the fact that people did eat meat during the feast in the first place and no restrictions were made.
I'm a vegetarian... Read Ex 12-15. The festival prohibits yeast, as it takes time to rise. If you can cook meat quickly, then there's no reason to prohibit it.
