Not Quesadilla policía... however some hints to transcendent crunchy goodness:

-toast the insides first. Crisp one side of tortilla. Put toppings on it. Crisp other side and put on top. Crispy faces insides. Continue as before. Flip. Etc. This makes it 2x crispy and reduces time to melt. -use white melty cheese like Munster or Monterey jack, Oaxaca or heck mozzarella.

Add cilantro, drained chorizo/soyrizo sauté some onions and jalapeños. You are doing great, better is potentially available.

So, it's simulated Beaver anal glands?

All clothes are tubes.

Meatsack tubes.

Sock tubes. Cock tubes.

I'm sort of agreeing that this might be closer to a 1973 timeline because of the Camaro R2 or potentially AMC Javelin in the illustration, however it could just be some graphic design of both/similar vehicles... mid to late 1970s seems close enough.

At the bottom of the bold text. Trademark, you see 1977 in the ad.

If making a soup, then they will cook in about 5 minutes. So peel and clean and add them at the end.

If you're adventurous, boil the shells and strain the water for shrimp stock, then make the soup base with your vegetables and then add them at the end since they cook quickly.

I'd recommend adding butter and cream with dill and lemon... or maybe add fish and make a seafood stew with a tomato base.

Good luck!
