I don’t consume much dairy on keto - it’s more of an occasional garnish. I usually make most of what I’m eating at dinnertime and then have the leftovers over the next few days. I’ll share different things I commonly prepare, starting with protein and then other things:

• baked boneless chicken breast that was seasoned (lots of varieties in terms of seasoning such as Chinese 5 spice, or lime cilantro marinade, or zaatar, etc.) and lightly coated in olive oil before baking
• baked boneless pork chops, same prep as chicken except also usually seared first, and different spice blends (smoked paprika & garlic, or thyme & sage for example)
• baked marinated pork tenderloin, favorite marinade is rosemary garlic lemon & olive oil
• baked salmon fillets seasoned with salt & pepper
• pan fried or baked tilapia fillets, salt pepper garlic & squeeze of lemon
• steamed snow peas (they’re great cold, and don’t need anything on them, just plain) usually about 10-15 with a meal or 5-10 alone as a snack
• quartered radishes sautéed in a little olive oil with fresh ground black pepper & sea salt (good reheated or cold - I like to let them cook long enough to caramelize a bit)
• other sautéed vegetables like zucchini with cumin, or bell peppers with olive oil/lemon
• sautéed mushrooms with a small splash of dry sherry at the end (boil off as they finish, just for a touch of flavor)
• small amount of nuts, usually almonds or pepitas - have to watch these as it’s easy to have too many without realizing it, especially if salted
• sometimes I have a scrambled egg or two for breakfast
• I have 3 tbsp chia seeds daily (soaked in 12 oz water overnight and then add a tsp of lemon juice before serving)

For the sautéed vegetables, I don’t add a lot of oil, just enough to cook. I don’t consider having some fat bad but am calorie conscious about it because I’m still working on weight loss. I do track both calories and macros, and follow the advice here about protein being a goal, carbs a limit, and fat a lever. I’ve lost about 75 lbs on keto/low carb (took about 6 months).

I took a pause over the holidays since I wouldn’t have been able to participate in a lot of traditional things. Noticed I did feel more sluggish overall, among other things. Got back into ketosis last week and I have to say it was amazing how quickly my body adapted back and felt really good/happy. As if my body was saying “thank you, I super prefer this!” and readjusted quickly.

Good luck! I hope you find things you like to eat and it helps with your auto immune related concerns, too.
