In the hot weather like this, it's a very good idea to enjoy Rujak! It's very traditional Indonesian mix fruits salad, usually contents fresh firm fruits available during that time i.e : mango, pineapple, cucumber, guava, papaya, etc, etc.
Here in UK I choose to have mango, pineapple, cucumber, apel, pear & strawberry.
For the sauce it's simply mix of :
1 (or more) Bird eye chilli / Cabe Sesuai Selera
1/2 tsp Salt
2 tbsp Fried Peanuts (1 tbsp Crunchy Peanut Butter) / Kacang Goreng
150 gr Palm Sugar / Gula Merah
