Beef and lentil shepherds pie with potato cauliflower mash

When it comes to fertility, there is significant research to support that substituting animal protein for plant-based proteins (such as lentils, chickpeas, and black beans) can improve our chances of ovulating significantly. We also know from the research that the more non starchy veg that we can add to the diet, the better! This supports a healthy gut microbiome, balanced hormones, healthy ovulation, and so much more.

This pie is an example of a way that you can add some more plant-based proteins into the diet without going full vegetarian. We are all about addition rather than subtraction when it comes to diet so give this one a go and let me know how you find it! Tag me in your story if you make it @dietitianalex_ - I would love to see!
