Wash and dry the radishes and keep the greens intact or trim them within 1 inch, then thinly slice the radishes. Transfer the radishes to a medium bowl along with the shallots and salt, toss to combine, and let stand for 5 minutes.
In a bowl, whisk the rice vinegar with the soy sauce and drizzle in the olive oil, whisking until emulsified. Add the cilantro and half the dressing to the radishes and toss gently to combine. Transfer to a platter, top with the goat cheese, and serve the remaining dressing on the side.
Combine black-eyed peas, sweet & hot peppers, cucumber, red onion, green onion, tomatoes, half of the parsley, and fonio/quinoa in a large bowl. Gently toss.
Combine oil, vinegar, tahini, garlic, honey, paprika, salt, and pepper in a small bowl. Whisk well and add water to thin if needed. Taste and add more honey if needed.
Pour vinaigrette over black-eyed pea mixture and stir well. Taste and add more salt or pepper, if needed. Refrigerate at least 1 hour for flavors to meld. Garnish with remaining parsley just before serving.
