This week we've been asking you to imagine your lives in 2040 with our series about the future of water in California. As KPCC's Sanden Totten reported this morning, eating drought-friendly may one day be as common as eating organic or locally sourced foods. These are meals with ingredients that take comparatively less water to grow and produce.

With that in mind, we met with Chef Wesley Avila of Guerrilla Tacos for his recommendations on how to cook a drought-friendly meal — in this case, how to make a delicious and drought-conscious veggie taco.

1. To make the sweet potato tortillas, use 4 medium-sized sweet potatoes; wrap them in plastic wrap and nuke in microwave for 10 minutes or until soft. 

2. Place 3 to 4 cups of all purpose flour in a bowl. 

3. Add crushed and cooked sweet potato; add eggs, season with salt; roll into golf-ball sized balls and set aside. Let masa rest 45 minutes before rolling.

4. Use extra flour to dust your hands and any tortilla press/rolling pin you use, then press the balls to get discs about a 16th of a inch thick.

5. Roast the tomatoes, serrano peppers and garlic until nicely charred; in a pan slightly toast guajillo chili, sesame, and pumpkin seed; add tomatoes, garlic and serrano peppers; cook about 7 minutes on medium; season with salt and add 2 tbs vinegar to blender or food processor until blended.

6. Grill all veggies until done cooking; remove from grill and set aside and slightly cut into bite sized pieces.
