Here a idea for your 4th party that might wow some of your guest.
A few years ago for a 4th of July get together, I made deviled eggs. No big deal.
But I did add a the 4th theme to them. What I did was take some easter egg coloring (red and blue) and after peeling eggs and removing the yolk like you would for the regular deviled eggs I took a 1/3 of cooked egg whites and put them in the red coloring, a 1/3 in the blue, with the final 1/3 left plain. Then I put the egg filling in so that there was red white and blue deviled eggs.
Sorry no pictures but think you will get the idea.
