Just the 2 of us too. About 2/3s of the time we prep and cook together. Leftovers tend to be make your own plate.
Dishwasher died at beginning of lockdown so we eat watching Jeopardy (MST) and hand wash and dry dishes together during Wheel of Fortune. It is fun.
Here in Indy it’s WOF first and Jeopardy second. That’s the same time as we sit down to eat, too. For leftovers, if there’s not enough for a whole other meal for both of us, we may use some as an appetizer, or sometimes we come up with entirely new dishes created from the leftovers. As an example, grilled (or baked) chicken leftovers can be tossed on a salad with sautéed corn and salad veggies of your choice. Throw in some sliced avocado, tomatoes, and Colby Jack cheese. Top with ranch dressing that’s been jazzed up with chipotle seasoning, and now the salad takes on a South of the border flare. Even more fun with tortilla strips or wedges.
After we use roast pork for dinner, we might use the extras to make Cuban sandwiches, something I love from youth.
We absolutely love leftovers, especially when they show up as something totally different a few days later. We try hard not to waste any food, especially these days when groceries cost an arm and a leg.
