The recipe is a pesto style filling for mushrooms that invokes spice and Mexican ingredients. If you want to substitute a hotter pepper, the ingredients promote the heat rather than temper it. (Learned the hard way.)
Preheat oven to 350o.
2 jalapeños
4 garlic cloves
2 scallions
2 tomatillos, peeled of paper
¼ cup chopped cilantro leaves
1/3 cup shredded cheddar cheese or queso fresco
½ cup pepitas (pumpkin seeds)
4 TBS oil, divided
¼ – ½ lb. chicken sausage (optional)
4 mushrooms, chopped
8 large button mushroom caps or 2 portobellos
Wash vegetables, removing stems and roots. Heat cast iron skillet on HIGH and add 2 TBS oil. Toast jalapenos, garlic, scallions, and tomatillos until seared on all sides. Remove from heat and let cool for a few minutes.
In food processor, add cooked vegetables and process. Add pepitas and cilantro, process. Slowly add remaining oil in a slow drizzle with machine running. Scrape down sides. Add cheese and chopped mushrooms, process. If adding sausage, process last.
Remove stems from large mushrooms and wipe grit off caps with a damp paper towel. Wipe caps again with oil. On a baking sheet, either oil the bottom or use parchment paper. Fill the caps with mixture and place on baking pan.
Bake 30-40 minutes. Tops will be browned.
Refrigerates well for leftovers.
