When I lived in Houston, I loved to stop at El Rey Taquería for a big bowl of their tortilla soup, which was packed with chicken, shredded cheese, corn, avocado, and crispy tortilla strips, and also called caldo tlalpeño. The restaurant is open until 3 am on the weekends, and has a drive-through. I miss living the easy life in H-town, with all the drive-throughs, cheap prices, and delicious Mexican food! I decided it was time to make my own caldo tlalpeño up here in the frosty north.
A little research revealed that caldo tlalpeño and tortilla soup are not really the same thing. Tortilla soup usually has tortilla strips in it (shocking, right?), and caldo tlalpeño often has chickpeas and other vegetables like chayote. This is my version of the soup, which combines the best of both worlds. If you can’t find chayote (I found mine at the Vietnamese market), you can use zucchini instead or leave it out.
