Roasting potatoes is better than frying. Use a good oil like avocado oil.
Try smoothies. Use a fruit from the berry family. Blueberries are super nutritious. Add Greek yogurt or kefir (both have good pre and probiotics ), a bd a protein powder. Sometimes I throw in almond butter or almond milk. I use a ninja blender to mix. I drink as much as I want and save the rest for the next day.
Nuts are also an alternative to a meal. A handful of almonds are nutritious and contain protein.
