These are TJs. I used to rip them until it struck me to microwave for 10 secs, and wouldn’t you know it, they open right up without tearing!
ETA: I have been using big bags of frozen spinach as it seems harder to find fresh that isn’t mangled by the time I get to it. Sauteed with onion, garlic, chilli flakes (of some variety, olive oil, nutmeg, and a splash of vinegar or lemon juice at the end.
I use it up in this or the quesadilla version of gozleme, mixed into rice as arroz verde, or into lentil soup / dal.
