In a fairly large saucepan on medium heat, add the olive oil, leek, paprika, salt and pepper.
Let the leek soften (cook until it's pretty translucent), stirring occasionally.
.
Add in cauliflower, and stir until thoroughly combined.
Pour in the veggie broth and place the lid on the saucepan, and let this cook for about 10-15 minutes, stirring occasionally so as not to have the cauliflower stick.
Taste the mixture (carefully!) - add more salt/pepper if necessary.
If the cauliflower is still a bit hard, cook until it is softer, and more like rice.
Remove the mixture from heat and garnish with parsley.
Serve and enjoy!
