I’m assuming you mean “completely plastic free”. I’ve been slowly removing plastic and teflon from my kitchen and replacing it with wood, cast iron, glass, ceramic, and silicon as appropriate. This isn’t difficult at all, just expensive, esp if you have a lot of kitchen utensils.

I do meal prep and avoid eating takeout or frozen foods as much as possible, though I’m far from perfect.

I feel like this probably reduces my exposure to plastic particles by like 80% and the last 20% is unachievable unless I go live in the woods alone and hunt for food. So I’m pretty happy with it.

We're reducing where we can. We have two young kids and threw out most of their plastic plates and cups. We kept a few for their utility. Heat increases transmissibility, so don't put hot consumables in or on plastic and don't cook with plastics. Especially avoid plastic cooking utensils and styrofoam cups. Currently we have an abundance of food and drink options, so just go without at the convenience store, choose the metal / glass options when necessary, or plan ahead by bringing a stainless steel or glass bottle. Most stores will let you put coffee or drink in your own container - it actually saves them the cost of a cup. TFA recommends moving food from plastic and styrofoam containers into a glass one when buying take-out or from a grocery to reduce the time plastics have to leach into your foods. I've mentally equated it to smoking a cigarette.
