Learning how to cook healthy meals that my kids will still eat has been the biggest challenge for me. My middle child won't eat anything at all - if it is labeled "dinner" she just won't eat. It gets so discouraging trying to cook healthy for 4 other people that I often just go back to comfort foods. We end up eating a lot of grilled cheese and pasta (which they still won't eat). I'd really love to find some healthy meals that my kids will actually eat.
Also, how do you get quick food out and get something that is absolutely terrible for you. My husband doesn't cook, so when if I don't feel like cooking one night we end up eating shitty food. Need to figure out how to add something easy that he can help with that isn't really bad.
And yes cutting out sweets. That is for sure my biggest weakness. I have terrible cravings for something sweet so I really just need to clean all that crap out of my house and go cold turkey. Makes me sad.
I really, REALLY hesitate to give advice on how to get kids to eat healthy because I don't have any and don't know what it is like being a parent. That being said, if I didn't want what my mother made for dinner she'd say that's fine you must not be hungry and I wouldn't get anything else. I also wasn't allowed to raid the fridge for the rest of the night either, with the exception of that night's leftovers.
But, I always remember it being that way. I imagine it is much harder and more stressful to start that kind of thing when your kids are older.
As to quick/easy meals, it takes a bit of effort in the beginning but eventually you pick up some "go to" things. My super lazy go to snack is some cottage cheese and an apple, but that isn't a meal. Monday (and sometimes Tuesday) night's meal is almost always the stew I made on Sunday reheated in the same pot. It generally even tastes better the next day. For a quick salad I dump a bag of spinach in a bowl and dress it salt, pepper, garlic powder, some dried spices, olive oil, and red wine vinegar. Additional veggies are cut up and added to my level of ambition.
Meat and fish are really fast and easy to cook in general. Slice the meat into ~3/4 inch slices, some butter in a cast iron pan, ~2 minutes a side and then its done. Fish is even easier, some lemon juice and dill, throw it in an oven for 20 minutes and it is done. You can cook it in a pan too but that is more effort.
Homemade Tzatziki is fast and delicious. Find some good, plain, full fat Greek yogurt (Or in my case it's Turkish). The only ingredients should be milk, cream, and bacteria culture. Grate a cucumber and mix in salt, lemon juice, olive oil, mint (fresh or dry), and garlic if you are feeling ambitious. Put that in the yogurt and bam there you have it. Makes no sense to buy since it is so easy to make and costs a lot to buy it fresh from the store.
I'll post more quick things as the come to me. I honestly don't even think about it anymore.
