To prepare a tempeh and vegetable chili beans and grains recipe, you will first need to prepare the ingredients. You will need: 1 pound (240 g) of scallions, 1/4 cup (60 ml) dried thyme, 1 tablespoon (2.5 tsp) kosher salt, 2 tablespoons vegetable oil, and 1 teaspoon (0.5 fl oz) vegetable bouillon cubes. Heat the oil over medium-high heat. Add the chopped onion and cook until translucent, about 5 minutes. Stir in the diced tomatoes. Cook until the tomatoes are soft, but not mushy, 3 to 4 minutes, stirring occasionally. Remove the onions from the heat and add the garlic, chili powder, cumin, oregano, paprika, salt and pepper to taste. Simmer the mixture, covered, for 1 to 2 hours, to allow the flavors to meld.
