Step 1

Place 1/2 tablespoon bouillon paste, 1/2 teaspoon miso, 1/2 teaspoon chili-garlic sauce and 1/2 teaspoon ginger in each of 3 pint-and-a-half size canning jars. Layer 1/4 cup carrot, 1/4 cup mushrooms, 1/2 cup spinach, 2 egg halves and 1/2 cup noodles in each jar. Top each with 1 tablespoon scallions and 1/4 teaspoon sesame seeds. Close the jars. Refrigerate for up to 3 days.

Step 2

To make one jar of noodles, add 1 cup of very hot water to one jar. Close the jar and shake to combine. Microwave uncovered on high in 1-minute increments until steaming hot, 2 to 3 minutes. Let stand 5 minutes. Stir before eating.
