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.
Cut Swiss chard stems into very small pieces. Tear leaves into 2" pieces and rinse well (you’ll want some water still clinging to the leaves).
Heat oil in a large skillet over medium-high. Add chard stems, shallots, and garlic and season with salt. Cook, stirring occasionally, until vegetables are starting to soften but haven’t taken on any color, about 2 minutes.
Add chard leaves, season with salt, and cook, tossing occasionally, until leaves are tender and have released some liquid, about 3 minutes (stems will have a bit of crunch).
Mix in vinegar; taste and season with more salt if needed
