I see you marked following diet recommendations has been difficult for you.  Please let me know in the messages how I can help further assist you with this.  In the meantime, here are a few suggestions that I like to give my clients:

Try and do some meal prepping one or two days a week. This is what has helped me personally. It's really hard to rely on packaged foods all of the time. I make a big batch of Quinoa or rice, cut up vegetables for the week, and make homemade hummus that lasts us a couple of weeks almost. That way I can quickly make veggie wraps or salads. I make soups and freeze them so I always have those available if I need. Also having different pre-made, cold bean salads or chickpea salads are fast and super easy so they are ready to eat whenever and pack well. Toast with goat cheese, walnuts, drizzled honey and rosemary is delicious for breakfast or lunches. Oatmeal is easy to pre-make and keep for a few days. Pinterest has been my best friend for meal prepping :)  

We also offer an amazing cookbook with a ton of information you can use for skin-safe eating. It offers about 2 weeks worth of meals with snack and desserts too. It can help you think outside of the box and not make your diet feel restrictive! I have included a link here if you would like to check this out. Clear Skin From Within Cookbook

Here are some snacks you can try, as well:  Rx bars or Lara Bars (no peanut butter), Siete chips with guacamole or hummus, goat cheese & crackers, beef or turkey jerky (no soy or salt, sea salt is okay), raw veggies & hummus, bananas or apples with almond butter, CHOMPS turkey or beef sticks.

Great alternatives for Cow's cheese are goat and sheet cheese

Miocos and Kithill are good cheese alternatives

Note: Canola Oil and B12 can show up in a lot of non-dairy products
