Spread the crackers in an even layer on a large rimmed baking sheet. Brush with melted butter and sprinkle with the sesame and poppy seeds. Bake for about 5 minutes, until lightly browned.
Meanwhile, in a large skillet, cook the bacon over medium-high heat until crisp. Drain on paper towels, and then finely chop.
In a food processor, pulse the peppers once or twice to chop them. Add the cheese, garlic, hot sauce and 3/4 cup of the mayonnaise. Pulse until the mixture is well blended; add more mayonnaise if it is too thick. Scrape the pimento cheese into a bowl and fold in the chives, almonds and most of the bacon; season with salt. Garnish with more chives, almonds and the remaining bacon. Serve with the seeded saltines.
