Pepper cut into strips.
I didn’t take any crackers. Options 2.
1 (Personally I like it more). Fresh white bread (it would be nice to have your own, freshly baked) cut into cubes, put on a greased baking sheet and at a temperature of 160 degrees, stirring occasionally, dry until golden and ready. Leave the right amount for the salad, pass the rest through a meat grinder and chop.
Option 2. Fry the bread cubes in a frying pan until crisp.
I always dry it in the oven, the crackers turn out less greasy and tastier.
