My mother just called it "the cold plate". :-)
On a dinner plate, place thin slices of cucumber, tomatoes, black olives, green pimento olives ( you can leave these out ) ,sliced radishes, green, red, and/or orange slices of pepper/s, slices of avocado ( if you like them, or you can stuff the center with the shrimp or chicken salad ), and decoratively cut spring onions ( if you like them )in a decorative design. Add peeled cooked shrimp or shrimp salad or chicken salad and serve with a light salad dressing, on the side, IF desired for the veggies...and cocktail sauce for the shrimp cocktail, IF you use the shrimp that way.
Yum!
Sounds good, and refreshing! I will go with the shrimp salad :-)
