This dressing has a nice lemony kick. Lemons are considered a health-giving food in Ayurveda because they stimulate the digestion and are both cleansing and nourishing. Refrigerate any leftover dressing and use within 3 or 4 days.
In small saucepan, heat 1/3 cup sesame oil over low heat. Add asafetida if desired and sesame seeds and cook, stirring often, until sesame seeds just begin to turn golden, about 6 minutes.
Add bell pepper and cook until sesame seeds are well toasted, about 5 minutes. Add ginger and stir once or twice to coat with hot oil. Remove from heat and let cool for a few minutes.
Transfer sesame mixture to blender or food processor. Add lemon juice, sugar, drizzle of sesame oil and 1/3 cup water. Blend until as smooth as possible, ad-ding more water to thin if necessary. Add liquid aminos and freshly ground pepper to taste; blend again.
