Do you or the wife use Pinterest at all? It's a great tool for finding and tracking idea, recipes, DIY stuff. I highly recommend it for situations like this.
We too, eat versions of Mexican and Italian, along with breakfeast for dinner fairly regularly. Homestyle cooking like soups and dutch oven bakes (roasts/whole chickens/etc.) are also a staple in our house. That's why having versions of these "bullet points" are important and Pineterest really helps with that. I often make a protien, then pair it with salads and a cooked veggie or too. Once a week I prepare a veggie tray of raw veggies and that's always on hand, often as a side for dinner since the girls like to pick at it, as do I while I'm cooking.
One go to that we all love is my version of "dirty rice". I use a quality wild rice blend, mix in ground vension that I cook with a mixture of brown butter, carmelized onions, and garlic, then finish with black beans. I typically douse my in hot sauce and have been known to also mix in quinoa to get more fiber in everyone's diets. Another go-to that's as easy to prepare as dirty rice and keeps in the fridge as well is beef and noodles. That's my wife's fav. I use good egg noddles and venison, sometimes canned, sometimes steak slice thinly. Cook venison in butter and garlic, remove from pan, then add beef broth and make a nice gravy. Add venison back in, along with noddle, toss to coat. We pair cottage cheese with a lot of meals and its a must for this meal!
A goal this winter for me was to diversify my cooking, so I've been look at other cuisines and "one pot" dishes as ways to do that. However tonight is whole roasted chicken with fingerling potatoes and a medley of cooked carrots. We'll also have salads (spinach) which are had at about every meal in our house so people get their greens.
