Stew. That had been a fairly easy, warm, winter food that Tonks thought herself capable of cooking, would be healthy for both of them, and would take most of the day in distracting her from the fact that Remus had not come home yet, even though he could write in his journal. Why wasn't he back? Had he gone that far into the woods? She wasn't entirely certain, but it was the first moon she ever really spent with him (or not really with him), but while they were living together, and she had hoped to see him almost immediately after the mess was over.
So, she took a big pot, tossing in all sorts of veggies, potatoes, chicken and beef cubes and let it simmer the whole day. She'd consulted a muggle cook book about it all and found the recipe to actually be nearly impossible to mess up. Only one incident of boiling the pot over, and she actually had an apartment that smelled like good food and was full of warm heat. Hell, maybe that was the pleasure that Molly Weasley felt on a routine basis. It was good cooking for the people you loved.
She jumped from her place in the kitchen as she heard the door open and his voice echoed a moment later, "Remus!" She breathed out, relieved and worried all at the same moment. She scampered across the flat, managing not to trip for once, so she could greet him at the door and take everything about him in. "How are you? Are you hurt? Cold?" She asked, hovering and worried.
