Frustrated because I stay hungry

You can make tuna salad with greek yogurt instead of mayo. It is a bit tangy, but it tastes good, IMO. I would ditch the crackers and add a better snack - a piece of fruit and some nuts (almonds are my favorites), some veggies and hummus, etc. Personally, I'm not a fan of eating sandwiches, but that's just me. I eat a huge spinach salad with tuna or chicken on it every day for lunch. It is a great way to feel really full and satisfied without taking in a ton of calories. Plus, the greens and veggies are really good for you!
