That's what I call the ones on my list, since all are obviously not leafy but count high nutrient-wise.
SUPER GREENS ---
Spinach
Broccoli
Oriental Greens (pak choi, Chinese broccoli, etc.)
Okra [lady fingers]
Dark Salad Greens (any dark green or even red type lettuce, including romaine/cos, lamb's, minzuna, oakleaf, ruffled, watercress, rocket, etc.)
Podded Peas (snap peas, mange tout)
Green Beans
Kale
Cabbage and Cabbage Greens
Beet Greens
Green Beans
Brussel Sprouts
Courgettes
Other veg is great as well on LC, like cauliflower, aubergene, yellow crookneck squash, mushrooms, celery, cucumbers, etc.
Hope this helps!
