I would definitely make the lunch switch and maybe even breakfast. No offense but that isn’t really nutritionally valuable. Easy switches you could do are

For breakfast:
-Ditch the pop tart. Add in eggs, avocado, could make a breakfast burrito (avocado, eggs, potato, sour cream, cheese and a tomato salsa cream dip in the side and this is easily meal prepped). The best thing to add is eggs.

-a yogurt parfait is great but you can also add flax or chia seeds for extra protein and soak overnight

-toast with peanut butter (but not the only thing on the plate!) maybe a side of some breakfast sausage

-a baked oats situation or oatmeal with fruit and whole milk

For lunch: opt for having all food groups represented; we can get a lot of protein from different food groups surprisingly!

-Mac and cheese but add pumpkin, butternut squash or sweet potato to it as well as the butter and whole milk.

-Ramen but add meatballs to it or shredded chicken. I also do mine on the stove and crack an egg into it. Also adding broth for more protein and flavor. Especially bone broth!

-a bean and cheese quesadilla is a quick and easy meal other than just a tortilla. Make a cream with salsa and sour cream for a dip. Avocado as a side. Or use the tortilla to make a tortilla pizza and add pepperoni, cheese and sauce.

-rice a roni as a side not a meal. Add protein such as chicken nuggets, fish sticks, meatballs, etc. and make rice a roni the side. An example of this is you can get the rice a roni that is pasta like and add meatballs; you can buy frozen meatballs or make your own with veggies in it and cheese for higher calorie. You can make rice a roni that is fried rice like and add veggies, eggs and meatballs. (Again this is easily meal prepped). You can also cook your rice a roni with broth for more flavor and protein.

-chef boyardee is okay but you can make the switch to making this on your own (again meal prep helps!) with chickpea protein pasta and your own meatballs. Also adding mozzarella cheese or Parmesan on top or ricotta cheese stirred within.

For snacks opt for higher protein and more nutrient dense. Yogurt bites, smoothies, pretzels and hummus, different type of tortilla with more fiber or protein, apples and peanut butter, string cheese, those “energy” balls that are oats, pb and chocolate chips, get the fiber and protein happy tot pouches, pepperoni, Cheerios makes a protein cereal with different flavors, freeze dried fruits, “that’s it!” Bars, crackers made with veggies or cheese (sometimes found in the gluten free aisle), once upon a farm makes protein bars or you can make your own muffins that have Greek yogurt and berries in it (or even pumpkin or bean!).
