Wash yellow beans thoroughly
Place beans in a saucepan with boiling water. Keep boiling for 5 minutes then immediately run through cold water.
Strain through a colander and leave on a side to cool completely.
Cut yellow beans in small pieces, about 1/2" long then place in a large mixing bowl.
Crush garlic and mix with mayonnaise, salt and pepper to taste (optional, add chopped dill too).
Pour the mayonnaise garlic mixture over the yellow beans and mix to coat.
Perfect to serve cold, with pickles on wholewheat bread with seeds.
