Stir Fry
Pita sandwiches
Flour Tortilla 'sandwiches' (those rolled-up types)
A nice good soup. Even if bought already made.
So, sandwiches, salad and a soup.
And some kind of beverage.
Salad Dressing??? There is SO many different types in the store.
Pick an Asian one, a typical vinaigrette, and then maybe a French dressing. 3 kinds. Then you, pour the dressings into cute petite sized bowls, put the little bowls on a nice platter, with a teaspoon with each one, and service it that way. So that your guest can ladle a dressing on her salad, of her choice. Along with that, if you have ground pepper, that is a nice added touch, for a salad. If she likes pepper.
It is about "presentation."
It makes, even store bought food, look nice and 'special.'
Serve your sandwiches on a nice round platter.
And the salad on a nice platter too, that you 'build' up.... visually. Decoratively.
And, cut the sandwiches. One sandwich made with a normal slice of bread for example, can be cut into... FOUR pieces. In triangle or square shapes. Cut off the crust, to make it look even more special. And serve on a platter for you both to self serve.
Being it is just the 2 of you, you don't need a ton of food.
You can go to your local grocery store deli, buy a bit of chicken salad filling for the sandwiches or turkey deli meat, a bit of lettuce, the bread (whole wheat or rye), buy store bought soup from the deli too, and even the salad. Easy.
It may be, that even if you made it all yourself from scratch, it may cost more, than buying it already made.
