Aldi is generally decent meat at a good price (at least in my area). Yes you can eat steak every day.

Air fryers are a decent way to go, I have a ninja. Unfortunately it seems like a good idea to avoid aluminum cookware & nonstick surfaces (which I haven't fully eliminated yet) 😢 nonstick pans apparently realease some sort of silicone oil. So stainless steel & cast iron are the healthiest options. If you have a pan you've been using don't let perfection keep you from getting started, just plan to upgrade appropriately when the time comes.

I have a glass top stove, I turn the eye that fits my pan on high, let the pan warm for a minute or so, throw a steak on with a glass lid. If the stove is hot enough when the top of the steak begins to change colors then you can take the pan off the eye, let some of the sizzling slow for a sec, flip the steak, replace the top & put it back on the heat. Cooking this way gives me a nice sear on both sides, and leaves it pretty rare in the middle. And the top prevents a lot of the mess. Afterward, if you wipe the stove kind of in a single direction around the eye using a warm wet paper towel, that really helps lift the oil off the top & make it easier to clean with a surface cleaner once the stove is cool.

It helps to have a decent knife & maybe a cutting board from target or somewhere to eat off of so you don't constantly dull your knife. I wipe my cutting board down with coconut oil every time I eat & afterward rinse with warm water while wiping any food residue off with a paper towel, & then drying well with a fresh paper towel. If you oiled it well & then rinsed it well there shouldn't be anything on it anyway, but bacteria can't survive in the wood once it's dry. I have a couple cutting boards so that I can alternate & they get plenty dry between uses.
