Hmmm... ok I think this is what you are trying to do:
If I am understanding correctly, you have a link in your sidebar called Recipes, and when I click it, it brings me to a page you created called "Recipes". There, I see you listed abunch of things you want to make into links (Breakfast, Lunches, Dinners, etc) that will direct you to your tagged posts. Am I correct so far?
Using the Lunch link again, your link redirects me to "
https://chrissywojo.tumblr.com/Lunches" but there isn't anything there (probably because you don't have anything there yet or haven't set anything up.) If you change the link to "
https://chrissywojo.tumblr.com/tagged/lunches" all of your lunch recipe posts will come up. And when you create new posts that have the tag "lunches" they will show up too.
This way might be easier for you and less confusing for others:
1. When you go to "Edit Theme" section and it pulls up that customize side panel, scroll all the way down to the "Pages" Section and add a new page.
2. When the "new page" thing comes up, go to the top area, it should say "Standard Layout".
3. Click that and select "Redirect". The page layout stuff should change.
4. Next to the "Redirect" there should be a box that says "Show a link to this page." it should be greyed out. Click it to "un-grey" it.
5. Where it now says "My Awesome Page" type in the new name of your page. So if this is your Lunch recipes page, type "Lunch Recipes".
6. The next box down should say "chrissywojo.tumblr.com/url". get rid of "URL" and put "lunches" (This is your new page that will direct to the tagged page I should you in the previous post.)
7. The next box should say "Redirect to" - type in "tagged/lunches". (This is where you tell it to redirect aka what tagged page you want.)
IMPORTANT: Ignore everything happening on the left side of your screen. It wont preview the page correctly.
8. Click Save
Your sidebar should now have "Lunch Recipes" as a link and when you click it, it will redirect to your "lunches" tag page.
Sorry if this is confusing. I think that way might work a little better for you.
I tested it out using your theme on my tumblr if you want to see what the finished product looks like: awfullybigadventureee.tumblr.com
Instead of "Recipe" pages I have "Quotes" and "About Me" as an example. (Im working on redoing my tumblr, my theme was 3 years old and didnt work anymore.)
