  1. I see you have lemons in the photo, but limes are listed on the recipe. Do both work or does lemon taste better than lime? Thanks!

  2. It looks like in the picture some red bell pepper or chili pepper was used. Did you decide to omit this from the recipe? I don’t see any on the list.

  3. 5 stars
    Delicious healthy high protein and meatless meal! I made this recipe today and I’ll definitely be making it again. I used a lemon instead of lime and I didn’t add the cheese. So good!
