Divide the house into two areas: upstairs/downstairs, main floor/basement, north/south. Whatever. Decide who gets which part of the house.
Each of you find 3 non-perishable food items the other likes. Attach a note to each item, a coupon redeemable for something you could do together.
Now each of you hide your items in your half of the house.
Take turns searching for one item while the hider looks on. You can always do “getting hotter/colder” to help.
Once all items are collected, decide which coupon will be redeemed first.
Try this and let me know how it goes.
