Question:
Hello, could crackers be used in place of bread/challah? (for example triscuits?)
Answer:
Essentially, we should be eating bread, challah, etc. for the first two Shabbos meals, and not crackers, cake etc. If one is stuck in an extreme situation then there are times when it would be permitted.
As a side point, there are times when people cut corners regarding the Shabbos day meal and want to only eat crackers instead of challah. This is an incorrect practice, in fact the most prominent meal of Shabbos is the day meal, and if one only has a special dish for one meal it should be served at the day meal.
Best wishes
