Re: Would you serve Cheese and Crackers to a guest in your home?
Cheese and crackers are often served at hotel conferences and professional development meetings. They are served as appetizers even during formal occasions. Nothing wrong with that at all. Some people don't go beyond serving just drinks to their guests. Know what I mean?
And Halwa, one can make simple foods look classy and elegant depending on the way they are plated or served. Put something in a pretty dish...arrange crackers in domino style and cut slices of cheese and it can look very nice.
Another option is to prepare the crackers before hand. Take several crackers and place a thin layer of cheese on top and garnish with diced tomatoes, or olives, or peppers. And serve. No need to be self-conscious....you're fine! If they showed up unexpected....they shouldn't be expecting a lavish meal. They're lucky they're even getting crackers and cheese ;)
