The Sims 4 Kits - Bite-size packs, big possibilities

The kitchen kit comes with two new recipes.

The tuna casserole and vegetable casserole can be prepared at level 10 of the Cooking Skill. Visually, they look the same; the vegetable casserole is just a vegetarian alternative to the tuna casserole.

ETA: Unfortunately the information on the two new recipes is incorrect. These were already available in game.
