Watercress Soup with Nopalitos

Food is how I show love in my home.

When words are not enough, I cook. For my son Emilio, that usually means Cochinita Pibil, the dish that instantly lifts his mood. For my Miah, it’s a fresh ceviche that makes her smile every time. And for my husband, who is a little particular with food, it’s Mexican flavours that always win him over.

His favourites are Ensalada de Nopalitos and anything with watercress. So one day, I decided to bring them together into something new: a silky watercress soup topped with a fresh Mexican cactus salad.

The result was unexpectedly perfect, light, comforting, fresh, and full of texture. This Watercress Soup with Nopalitos Salad is now one of our favourite quick meals.

If you love Mexican-inspired healthy recipes, cactus recipes, or light vegetable soups, you’re going to love this.
