Speaking of cheap meals, here's a nice lunch for $1 a serving. Basically, you make a big batch of the roasted tomatillo salsa you see right over there in the sidebar and purée it in a blender with a little water. Do that ahead of time. Then fry 3 corn tortillas (not flour) one by one in some oil about 20 seconds per side until crisping but not crispy. Dip both sides of the fried tortillas in the tomatillo purée and fold on plate. Top with more purée, shredded cabbage, sliced radishes, and crumbled queso fresco. Season with salt and pepper. It sounds a little weird, I'll admit, but talk about great Mexican flavor with lots of fresh veggies. Don't knock it 'til you try it.
