Senegalese Onions

Ingredients

• 6 onions (medium, white or yellow, not sweet or mild, sliced thickly - 1/3 inch slices)
• 4 garlic cloves (quartered)
• 1 cup vegetable oil (a mild oil, not olive oil)
• 1/2 cup whole grain mustard (not dijon)
• 1/4 cup brown mustard (basic, supermarket brand, not sharp)
• 1/4 cup lemon juice (embarrassed to say, I use jarred)
• 1/2 cup water
• 1 bay leaf
• 2 teaspoons bouillon (I use Better than Bouillon, chicken, but you could use the vegetable bouillon or two cubes)
• 1/2 teaspoon white pepper (I use white pepper because it adds a peppery depth, without any heat, but black pepper is better)
• 1/2 teaspoon salt
