Notes
Here are some tips and tricks for making this recipe:
Use freshly squeezed lemon juice instead of bottled juice. The flavor is fresher and will work better in this recipe.
Don't overcook your pasta! Cook just to al dente so that it holds up with all the extras added.
Be sure to use utensils that won't mush the pasta when you mix all of the ingredients together. Using tongs or pasta forks will help ensure everything is well mixed and the pasta doesn't take a beating when you mix!
