Well I am a picky eater, so a lot of my meals consist of some lunch meat usually roast beef or ham because they tend to be lower in carbs than turkey, some cheese, typically sharp cheddar, mustard, pickles, and a couple of strawberries. My husband who eats anything though eats salads with lettuce, ranch (lowest in carbs we can find), cheese, ham, and some Whisps, which are basically crackers made entirely of cheese, in place of croutons. Eggs are also awesome on keto if you like them, I don't though so I stick to my typical meal a lot.
But really, it isn't as hard as some people make it out to be, just check every nutrition label for carbs and always subtract the dietary fiber for your net carb total and try to stay under 20g net carbs a day.
Ooh, and pork rinds! I eat them a lot with french onion dip as a snack.
Also, green beans are a fave of mine, 2g net carbs for 1/2 cup, that with some beef roast is awesome. And taco bowls!
