Fresh spinach?

Depends. I buy groceries every two weeks and get two bags of fresh spinach. I freeze one and leave the other in the vegetable crisper. So the first week it's all fresh, the second week it's frozen.

If you want more calories, try skirlie (oatmeal and spinach)

You tried kale before spinach? WTF? What's the story behind that?

Since the doctor's recommendation. Kale seems to have slightly more nutrients, but, IMO, at to great a cost too taste.

The kale taste can be mitigated somewhat with a mixture of lemon juice, olive oil, salt, pepper and sesame oil. I do this with spicy arugula too as I often find the taste overpowering.

Ah that makes sense. Still, I stand by my shock. Going to kale before spinach is just nuts (barring pressure from a doctor who doesn't care about your culinary experiences).

Have you tried cooking it though? Kale is one of the greatest stir fry ingredients

I had the misfortune of working at a company that chose to get us lunches from Zesty. I endured more varieties of kale preparation (and avocado which I also dislike unless made into guacamole) in a month than in my entire previous life. So many things were great about that job, but I was actually dreading lunch on most days.

I found it to be the other way around, spinach tastes gross and kale is rather neutral. Were you cooking it?
