Limes become easier to juice after freezing then thawing. I freeze whole lemons all the time. The pulp becomes softer and gives up more juice. Pretty sure the tomatillos would be fine if you are cooking and blending them. I buy frozen mushrooms mixes all the time and the texture of the cooked mushrooms are normal to me.
Good thing there were no fresh greens/leaves though. Those would have been a total loss.
