Put water to boil in a pan. Estimate the volume to cover the ramen noodles plus a little more for the kale you will add later. A narrow pan is best, which will maximize the water height and keep the volume reasonable.
Add the noodles, reduce heat and boil for 6-8 minutes until tender. Stir gently after 3-4 minutes to separate the noodles and make them even.
In the meantime, rinse and chop the kale. Discard the bottom of stems. Squeeze the lemon.
In the final 2-4 minutes of noodles cook time, add in the kale directly into the pan, then strain both.
Place the kale and noodles in a bowl. Pour the lemon juice on top, and finish decorating with the hot sauce.
