Equipment

kitchen thermometer
aluminum foil
broiler
broiler pan
Directions
Heat 2 teaspoons canola oil in a 2 1/2-quart saucepan over medium heat.
Add onion and garlic; saut 3 minutes or until mixture begins to brown.
Transfer onion mixture to a blender; add tomatoes, 1/4 cup water, espresso powder, cocoa, chile, 1 teaspoon Mexican seasoning, sugar, and 1/4 teaspoon salt. Process until smooth, scraping down sides if necessary.
Return tomato mixture to pan. Bring to a boil; reduce heat, and simmer, uncovered, 15 minutes or until thick, stirring often.
Preheat broiler.
While tomato mixture simmers, place pork on a broiler pan coated with cooking spray; brush with remaining 1 tablespoon oil.
Combine 1 tablespoon Mexican seasoning, kosher salt, and red pepper; rub over pork. Broil 16 minutes or until a thermometer registers 160 (slightly pink), turning once.
Remove from pan; cover with foil, and let stand 10 minutes before slicing.
