Not enough spinach for curry recipe

[Happytodayhappytomorrow]

And none in the freezer either.
Can I use half spinach and half kale?

It’s a Jamie sweet potato , chick pea and spinach curry.

TIA

I would cook the kale for a few minutes first. It will be fine I'm sure

I often substitute spinach for kale, its fine. Or chard.

Thank you both
