Spinach Rockefeller Stuffed Portabellas

READY IN: 45mins
Recipe by cmacooks

I love spinach in any form. I needed a vegetarian starter for a recent dinner, and found this to be just the ticket. The addition of basil makes it a little different than the standard Spinach Rockefeller.

I cut back a little on the butter. Sauted the onion and garlic together before adding the remaining ingredients. The recipe didn't say what to do with the celery, so I chopped it and added with the spinach. The lemon flavor was a little strong and if I were to make this again, I think I would reduce the lemon juice by half. I also think it would be good with additional grated cheese.
