Family Friendly Batch cooking

Batch cook (in crockpot) a vegetable dish and fry or broil some meat as an addition for the carnivores?

Suggestions:

• Lentil and vegetable curry (crockpot) with grilled Tandoori chicken
• Three bean chilli (crockpot) with grilled taco seasoned chicken pieces.
• Mushroom risotto (crackpot) with steak

Not a crockpot idea but, make pasta with a vegetable ragu and add meatballs for the carnivores.

How about mini meat loaves made in muffin tins? You could make up a batch of lentil loaves or bean patties or something to feed the vegetarian. Making batches of pasta sauce-- some with meat and some without would also be good.

Tonight I'm actually making a batch of vegan curry to share with a co-worker, after I take her portion out I'll add some chunks of cooked turkey to mine. Lasagnas would also be good to prep and freeze, I would maybe get a small casserole dish or similar dish so you can make up a similar-but different version for your vegetarian. Meat for the rest of the family, and maybe mushroom and spinach for the vegetarian. Two different versions of stuffing would be good too that you could stuff into zucchini or tomatoes, and you could do a similar thing with a rice stuffing to stuff bell peppers.

For your crockpot dilemma, either buy a small crockpot or just do your vegetarian batch cooking on one day or choose recipes that don't use a crockpot for your vegetarian. You could do your meat chili in the crockpot and make a bean only chili for the vegetarian on the stove.

Like @Maremare312 says, You need a collection of recipes that are tasty and nutritious without meat, but that you can easily add meat to for the carnivores. For example -

Baked beans + ham or bacon
Vegetable curry + any meat
Vegetable fajitas + beef or chicken
Vegetable stew + any meat

Cook the vegetarian base meal in the crockpot, and batch cook the meat separately, eg by roasting a whole chicken and breaking it down, or cooking joints of beef, pork, ham etc in the slow cooker, then portioning and freezing. That way you can easily defrost a portion of meat and add to the base meal.

Best way I've found to deal with different calorie needs at dinner is just to change portions and rebalance the amount of carbs - so my family eats a big portion of curry with plenty of rice, and I eat a smaller portion with proportionately less rice. If you are also trying to eat less, you might find this useful, it's a lot easier than trying to adjust the ingredients in the meal itself.

I batch cook a bunch of chicken thighs, shred the meat, and keep it in the fridge for use through the week. Use it in wraps, sandwiches and pasta and other dinners.

So you could make a nice stew or chili (meatless) later on and just add the chicken already cooked for whoever wants it

You make almost any pasta or casserole by preparing the meat on the side so people could add it if they wanted to. Thats what my mom does.
