In her cookbook, Lisa gives you all the tools and information you need to start living a healthier lifestyle.  It is so informative and breaks it down so it is so simple for you.

I love that her recipes are simple, healthy, delicious and can be made on a budget.

After having my baby three months ago, I am ready to get back in shape and lose my baby weight.

Lisa’s book has helped me eat healthier and improve my nutrition.  Every single recipe I have made from this book has been fantastic.

One of my favorite recipes from the cookbook is the Slow Cooker Flank Steak Fajitas.  They are one of the easiest meals I have ever made and are so amazingly flavorful and delicious.

how should i prepare my peppers and onions?

For this recipe, you will want your peppers and onions in thin slices. We have found that for fajitas, thin slices are best, because you can decide how much pepper and onion you want, compared to your meat ratio.

If you like more peppers and onions, you can add more slices, but I prefer more meat, with just a little bit of pepper and onion.

My husband piles it all on and like to make his into a burrito, pretty much.

    For the green bell peppers and onions, I don't see any directions on how they are to be prepared. I know the bell peppers need to be seeded. But before I put them in the slow cooker, what is recommended please? Sliced? And are the onions to be in wedges, or sliced? Thanks.
