looking for better solid solution

Hi I have this app that I making about create a food menu. I want to add to my list of foods for specific meal an ingredient. Currently I use naive approach that uses simple getting the value from button click. wanted to know if there is better why or more solidjs API for this instead. I saw there is createComputed and a lot more of other cool reactive function so I have wander how can I this power of reactivity inside my app more. Hope for suggestion or examples you know, I found the API doc little bit lucking of examples and implementation how should I use this functions for me. really hope this one will improve
