I totally agree about the simmering process. Protein (meat) should never be boiled. It also cooks very quickly. I’m not sure I’d cook 10 lbs at one time. Either buy smaller amounts or wrap & freeze if purchasing on sale & then thaw in frig & simmer.
You can easily shred (using 2 forks) a chicken breast & use it to make whole wheat enchiladas. Find a lo-sodium & lo-calorie enchilada sauce & mix shredded chicken in. Lay on a lo-cal whole wheat tortilla with some fat free cheese, roll, place in a pan with a small amount of sauce on the top. Heat till warm, top with a bit more cheese & serve. Very good.
Use the 100 cal bagels & layer a light pizza or tomato sauce on it, add shredded chicken & fresh mushrooms or other veg, again some Fat free moz cheese & pop in the oven briefly. When cold they can even be transported.
My all time favorite is to flatten a raw chicken breast & grill it outside. Cooks very quickly. Here we have a 35 calorie a slice whole wheat bread. Either toast it or have it plain & add that perfect chicken breast with a small amount of fat free mayo, lettuce & a tomato slice. Change it up & hae just the chicken breast with a few dill pickle slices.
There are so many easy simple things to do with chicken. Yes, soup is great, load it with veggies, you won’t even miss the noodles if the veggies are cooked perfectly. You could even start with some frozen veggies to save time.
