I live in El Paso, and have eaten at Casa del Sol from the night it opened until it closed, was the best restuarant in Juarez. I have never had cauliflower in their escabeche, also the jalapenos were sliced and the seeds were left. It was served in bowl with tortilla chips along with the salsa. You could make a meal off the escabeche and salsa if you weren't careful.
Brillant recipe thoroughly recommended
