Heat oil in a small skillet over medium heat. Add garlic and cook until fragrant, about 1 minute. Add watercress and cook, stirring, until just wilted. Remove from pan and set aside. Lower heat to medium-low.
Whisk eggs and season with salt and pepper. Pour eggs into pan and cook, stirring, until just set. Return watercress to pan and stir. Serve immediately.
I did this with 4 egg whites instead of eggs, and spinach instead of watercress. Delicious and easy!
I'm not a big fan of eggs but like them scrambled. This dish was pleasantly surprising to me. I've made it twice and will keep on making it!
