I made this yesterday and it tasted great.

Sauteed Greens
1 serving

olive oil
finely chopped shallot (1-2 depending on size)
3 stalks of diced celery
3 stalks of diced fennel
2 cups of greens -- I used a Trader Joe's mix of 4 greens (mustard, turnip, collard and spinach if I remember correctly)

Add 2-3 tablespoons of olive oil in a pan
Sautee shallot, celery and fennel until soft
Add greens
Cook until greens reach desired softness


Variation: Add diced red pepper for a bit of sweetness and color
